Reaction Steps
To a suspension of 4 mmol of lithium aluminum hydride in 20 ml of anhydrous tetrahydrofuran is added a 1 mmol solution of 10,11-dihydro-11-oxo-5H-imidazo[2,1-c][1,4]benzodiazepine and the mixture is refluxed for 24 hours and cooled at 0° C. To the mixture is added dropwise 0.12 ml of water and 6 ml of 1N sodium hydroxide. The mixture is extracted with ethyl acetate and the solvent removed to give the desired product as a solid. Recrystallization from methylene chloride-hexane gives crystals, m.p. 164°-170° C.
