Potassium Cyanide → HCID 54376131, compound

Participants

Reaction Steps

A mixture of 3.45 g (10 mmol) of ethyl (S)-8-chloro-11,12,13,13a-tetrahydro-9-oxo-9H-imidazo[1,5-a]pyrrolo[2,1-c][1,4]benzodiazepine-1-carboxylate, 100 mg of powdered potassium cyanide and 14.2 g of 3-chlorobenzyl alcohol is stirred at 130° for 48 hours, the mixture is diluted with about 20 ml of methylene chloride and chromatographed on about 300 g of silica gel while eluting with ethyl acetate. By crystallization from ethyl acetate and hexane there is obtained m-chlorobenzyl (S)-8-chloro-11,12,13,13a-tetrahydro-9-oxo-9H-imidazo[1,5-a]pyrrolo[2,1-c][1,4]benzodiazepine-1-carboxylate of melting point 114°-116°.
