実験手順
A suspension of 1.7 g. (4.87 mmoles) of 1-methyl-4-chlorocarbonyl-5-phenyl-7-chloro-1,3,4,5-tetrahydro-2H-1,4-benzodiazepine-2-one in 3.5 ml. of concentrated ammonia and 7 ml. of methanol is stirred at room temperature overnight. The mixture is diluted with 30 ml. of water, the separated crude product is filtered off, and recrystallized from ethanol without drying. 1.16 g. (72%) of 1-methyl-4-carbamoyl-5-phenyl-7-chloro-1,3,4,5-tetrahydro-2H-1,4-benzodiazepine-2-one are obtained; m.p.: 212°-215° C.
