点86℃。Example 12.7 g (0.1 mol) of N-cyanoiminothiazolidine was suspended in 150 ml of t-butanol, and
30% potassium hydroxide (KOH) in methanol
Add 0.66ml and warm to 40℃. On the other hand, a solution of 10.9 g (0.206 mol) of acrylonitrile dissolved in 10 ml of t-butanol is prepared, and this solution is added dropwise to the above reaction solution over a period of 40 minutes. After the dropwise addition is complete, the mixture is stirred at that temperature for 1 hour. The reaction solution is distilled off and water is added to the residue to obtain crystals of 2-(N-cyanoimino)-3-cyanoethylthiazolidine. This stuff is pure enough. Yield: 14.2g (78.8%). Melting point: 86℃.
