    摘要: Disclosed is a process for producing pure form of 2-methyl-4-(4-methyl-1-piperazinyl)-10H-thieno[2,3-b][1,5] benzodiazepine. The process comprises of reacting 2-(2-aminoanilino)-5-methylthiophene-3-carbonitrile with N-methyl piperazine in conjunction with N-methylpiperazine acid salt, to produce 2-methyl-4-(4-methyl-1-piperazinyl)-10H-thieno[2,3-b][1,5] benzodiazepine. Also disclosed is a process for obtaining the Polymorphic Form I of 2-methyl-4-(4-methyl-1-piperazinyl)-10H-thieno[2,3-b][1,5] benzodiazepine by crystallizing the crude 2-methyl-4-(4-methyl-1-piperazinyl)-10H-thieno[2,3-b][1,5] benzodiazepine in a mixture of solvents.
