(1) Preparation of Starting Compounds (III) (a) To a solution of 8.5 g. of 2-amino-3-benzoyl-5,6- dihydro-4H-[l]cyclopentathiophene in 100 ml. of chloroform is added, under ice cooling, 8.3 g. of N-benzyloxycarbonylglycyl chloride, and the resulting mixture is allowed to stand in an icebox overnight. The solvent is distilled off and the crude crystals thus obtained are recrystallized from ethanol to give pale yellow crystalline 2-benzyloxycarbonylacetamido-3-benzoyl 5,6 dihydro- 4H[l]cyclopentathiophene, melting at 114-115 C., in yield.
To 12 g. of benzyloxycarbonylacetamido-3-benzoyl-5,6- dihydro-4H-[l]cyclopentathiophene is added 30 ml. of a 20% solution of hydrogen bromide in acetic acid. The resulting mixture is stirred at room temperature, and 200 ml. of isopropyl ether is added. The crystals thus obtained are collected by filtration, washed with three 50 ml. portions of isopropyl ether, and 50 ml. of water is added. The aqueous solution is made alkaline with sodium hydrogen carbonate and extracted with chloroform. The extract is dried over sodium sulfate, the solvent is distilled olf, and the crude crystals thus obtained are recrystallized from ethanol to give pale yellow crystalline 2- aminoacetamido 3 benzoyl-5,6-dihydro-4H-[1]cyclopentathiophene, melting at l30l31 C., in 79% yield.
(b) Ammonia gas is introduced under ice cooling to a solution of 20 g. of 2-iodoacetamido-3-o-chlorobenzoyl- S-ethylthiophene in 50 ml. of dichloromethane and 5 ml. of methanol. After the introduction of ammonia gas for 2 hours, the solution is stirred at room temperature for 2 hours to complete the reaction. The reaction mixture is Washed with ice water and then with a saturated sodium hydrogen carbonate solution, dried over sodium sulfate, and concentrated under reduced pressure. The crystallization takes place on adding ethanol to the residue. The crystals are collected by filtration and washed with a small amount of ethanol to give 11.7 g. of almost pure 2-aminoacetamido-3-o-chlorobenzoyl-5-ethylthiophene, melting at 146-148" C.
(c) 2-azidoacetamido-3-o-chlorobenzoyl 5 ethylthiophene (5 g.) is added to 50 ml. of a 30% solution of hydrogen bromide in acetic acid, and the resulting mixture is shaken at room temperature for 1 hour. After the evolution of nitrogen gas ceases, isopropyl ether is added to the reaction mixture. The orange-colored gelatin-like substance thus precipitated is collected by decantation, isopropyl ether is added again, and the mixture is mixed well. The substance gradually solidifies. The solid is collected by filtration, washed several times with isopropyl ether, and dissolved in 50 ml. of chloroform. 5 g. of triethylamine is added, the resulting solution is allowed to stand at room temperature for 2 hours, washed with water and dried over magnesium sulfate. The chloroform is distilled off under reduced pressure to give white crystalline 2 aminoacetamido-3-o-chlorobenzoyl 5 ethylthiophene. melting at 146-148 C. (from ethanol).
(2) Preparation of Starting Compound (IH) To a solution of 2.5 g. of 2-iodoacetamido-3-o-methoxybenzoyl-S-ethylthiophene in 15 m1. of dimethylformamide is added, with stirring, 0.42 g. of sodium azide, and the resulting mixture is stirred at 60 C. for 30 minutes. After the reaction, 20 ml. of ice water is added dropwise to the reaction mixture and the entire mixture is cooled to room temperature. The red-brown gelatin-like substance thus obtained is treated with ligroin to give white crystalline 2- azidoacetamido-3-o-methoxybenzoyl 5 ethylthiophene. melting at 8384 C.
The compounds of formula (I) can be converted into the corresponding acid addition salts in a conventional manner by treatment with various inorganic and organic acids, for example, hydrochloric, hydrobromic, nitric, sulfuric, phosphoric, p-toluenesulfonic, citric, maleic, fumaric, succinic, formic, acetic and tartaric acid.
The compound of formula (I) and pharmaceutically acceptable acid addition salts thereof have excellent pharmacological activities in narcosis potentiation, suppression of fighting behavior and anticonvulsant effect as shown, for example, by the following tests.
(I) Narcosis Potentiation (II) Suppression of Fighting Behavior Fighting epoxides were produced in mice by the method described by Tedeschi et al. in The Journal of Pharmacology and Experimental Therapeutics, Vol. 125, p. 28 if. (1959). Eight groups of 8 female mice (4 pairs) were given the test compound orally 60 minutes prior to receiving an electric foot-shock for 3 minutes with 530 volts J interrupted direct current, 1.3 milliamperes, 10 cycles per second. Those exhibiting 3 fighting episodes or less within 3 minutes were deemed to be suppressed by the test compound. The control mice (81 pairs) had shown the fighting episodes of 8.7 times on the average under the same conditions. The'ED the dose required to suppress 50% of fighting pairs, was determined graphically.
(III) Anticonvulsant Effect Pentylenetetrazol (150 mg./kg.) was administered subcutaneously to eight groups each consisting of 6 mice, minutes after the intraperitoneal administration of the test compound. The number of dead mice were counted within 3 hours after the administration of pentylenetetrazol, and then the ED the dose required to suppress the lethal rate to 50%, was determined graphically.

EXAMPLE 1 A solution of 7.5 g. of 2 aminoacetamido-3-benzoyl- 5,6-dihydro 4H [1]cyclopentathiophene in 50 ml. of pyridine, 1.5 g. of acetic acid and 15 ml. of benzene is refluxed for 3 hours in a flask provided with a waterremoving adaptor. The solvent is distilled off, water is added to the residue, the solution is made alkaline with sodium hydrogen carbonate and extracted with chloroform. The chloroform layer is dried over sodium sulfate, the chloroform is distilled off, and the crude crystals thus obtained are recrystallized from ethanol to give pale yellow crystalline 5 phenyl 1,2,7,8 tetrahydro-3H,6H [1]cyclopentathieno [2,3-e] [1,4]diazepin 2 one, melting at 243 C. with decomposition, in 73% yield.
EXAMPLE 2 To a solution of 10 g. of 2-aminoacetamido-3-o-chlorobenzoyl-S-ethylthiophene in 50 ml. of pyridine are added 20 ml. of benzene and 1.9 g. of acetic acid. The resulting mixture is refluxed with stirring for 10 hours in a flask provided with a water-removing adaptor. The reaction mixture is concentrated, and the residue is extracted with chloroform. The chloroform layer is washed with water and then with a sodium hydrogen carbonate solution, dried over magnesium sulfate. The chloroform is distilled oif under reduced pressure, and toluene is added to the residue. Thus is precipitated white crystalline 5-o chlorophenyl 7 ethyl 1,2 dihydro-3H-thieno[1,3-e]- [1,4]diazepin 2 one, melting at 204-206 C. (from a mixture of toluene and ethanol).
EXAMPLE 3 To a solution of 4 g. of 2 azidoacetamido 3-0- methoxybenzoyl 5 ethylthiophene in 60 ml. of ethanol are added 2 g. of 5% palladium charcoal and then a solution of 0.3 g. of hydrazine hydrate in 10 ml. of ethanol with stirring. The resulting mixture is stirred at room temperature for 2 hours (nitrogen gas develops vigorously) and then at 50 C. for further 30 minutes. The insoluble catalyst is then filtered off, and the filtrate is concentrated under reduced pressure. The oily residue is crystallized 7 from hexane to give pale yellow crystalline -o-methoxyphenyl 7 ethyl 1,2-dihydro-3H-thieno-[2,3-e] [1,41diazepin-2-one, melting at l68l69 C. (from a mixture of ethanol and hexane).
EXAMPLE 4 To a solution of 8.3 g. of 2-amino-3-o-chlorobenzoyl- S-ethylthiophene in 40 ml. of pyridine is added 13 g. of ethyl glycinate hydrochloride, and the resulting mixture is refluxed with stirring for 20 hours. The pyridine is then distilled off under reduced pressure, and the residue is extacted with chloroform. The chloroform layer is washed well with water and dried over magnesium sulfate, and the chloroform is distilled off under reduced pressure. The red-brown oily residue is purified by silica gel-chromatography using chloroform as developing solvent. After removal of the first fraction containing the unreacted starting material, the chloroform eluate containing the object compound is concentrated under reduced pressure, and the residue is treated with toluene to give white crystalline 5 o chlorophenyl 7 ethyl-1,2-dihydro-3H-thieno- [2,3-e][1,4]diazepin 2 one melting at 204206 C. (from a mixture of toluene and ethanol).
EXAMPLE 5 5 p chlorophenyl 6,7 dimethyl-1,2-dihydro-3H- thieno [2,3-e][l,4]diazepin 2 one (3.0 g.) is suspended in 70 ml. of toluene. The suspension is heated to 40 C. whereupon 0.58 g. of sodium methoxide is added, and the mixture is refluxed to make a homogeneous pale brown solution. After about ml. of the methanol and toluene are distilled off, 1.3 g. of dimethyl sulfate is added slowly, and the resulting mixture is refluxed for 1 hour. After cooling, the toluene layer is washed with water, then with a sodium hydrogen carbonate solution, dried over sodium sulfate, and the toluene is distilled off. To the oily residue are added hexane and a small amount of ethanol. Crystallization takes place when the flask is scratched. The crystals are collected by suction filtration and recrystallized from a mixture of hexane and ethanol to give white crystalline 5 p chlorophenyl 1,6,7-trimethyl 1,2 dihydro 3H thieno [2,3-e] [1,4]diazepin- 2-one, melting at 182-184 C., in 76% yield.
