Reaction Steps

To a solution of 0.2 g of 5-(4-carboethoxy-1-piperazinyl)-11H-imidazo[1,2-c][1,3]benzodiazepine in 2 ml of dry tetrahydrofuran, 100 mg of lithium aluminum hydride are added at once and the mixture is refluxed under nitrogen for 48 hours. The mixture is cooled to room temperature, stirred with 0.2 ml of 30% sodium hydroxide, and filtered. the filtrates are evaporated to dryness and the product is purified to give 5-(4-methyl-1-piperazinyl)-11H-imidazo[1,2-c][1,3]benzodiazepine.
