Abstract

1377274 #-Aminobenzonitriles BADISCHE ANILIN- & SODA-FABRIK AG 29 March 1972 [31 March 1971] 14702/72 Heading C2C #-Aminobenzonitriles of the formula in which R is H, alkyl, alkoxy, phenyl, Cl, Br, NO 2 or CN; R is H, Cl, Br or NO 2 , or R and R<SP>1</SP> together are parts of a condensed-on benzene ring, are prepared by hydrolysing a compound of the formula or a salt thereof where R and R<SP>1</SP> are as above and R<SP>2</SP> and R<SP>3</SP> are identical or different alkyls, or one of the R<SP>2</SP> and R<SP>3</SP> radicals is phenyl or R<SP>2</SP> and R<SP>3</SP> together with the nitrogen form a heterocyclic saturated 4- or 5-membered ring. Hydrolysis of the amidines may be carried out in the alkaline range but preferably in acid range, e.g. pH 1 to 6. The hydrolysis may be carried out in aqueous or organic acids.
