Reaction Steps

A mixture of (3RS)-1-[2-(2-chloroethoxy)ethyl]-1,3-dihydro-3-(2-indolylcarbonylamino) -5-phenyl-2H-1,4-benzodiazepine-2-one (500 mg) and 1-methylpiperazine (5.0 ml) was stirred at 70° C. for 5.0 hours. Then diisopropyl ether (30 ml) was added to the reaction mixture. After the resultant precipitate was filtered off, the filtrate was evaporated. The residue was washed with water and dried to give (3RS)-1-[2-[2-(4-methyl-1-piperazinyl)ethoxy]ethyl]-1,3-dihydro-3-(2-indolylcarbonylamino)-5-phenyl-2H-1,4-benzodiazepine-2-one (0.43 g).
