Reaction Steps

Using the procedure of Example 2, 11-(3-chloropropionyl)-5,11-dihydro-6H-pyrido-[2,3-b][1,4]-benzodiazepine-6-one and 1-methyl-piperazine were reacted to obtain a 51% yield of 5,11-dihydro-11-[3-(4-methyl-1-piperazinyl)-propionyl]-6H-pyrido-[2,3-b][1,4]-benzodiazepine-6-one which melted at 232°-233° C. after crystallization from an ethyl acetate-ethanol mixture. The dihydrochloride thereof melted at 235° C. after crystallization from ethanol.
