Reaction Steps

A mixture of 7.41 g (0.025 m) of 3,4-dihydro-4-methyl-2-methylthio-3-phenyl-5H-1,4-benzodiazepine-5-one and 12.11 g (0.100 m) of phenethylamine is heated in an oil bath for 6 hours. The temperature of the oil bath is slowly raised to 240° C and held there for 1 hour. After cooling to room temperature, the residual oil is crystallized from ether to give the crude product, 3,4-dihydro-4-methyl-2-phenethylamino-3-phenyl-5H-1,4-benzodiazepine-5-one. Recrystallization from ethyl and ethyl acetate-ether gives a pure product, 3,4-dihydro-4-methyl-2-phenethylamino-3-phenyl-5H-1,4-benzodiazepine-5-one, a while solid, m.p. 173° - 174.5° C.
