8-Methyl-6-(4-methylpiperazin-1-yl)-11H-pyrido[2,3-b][1,4]benzodiazepine

The conformation of the title compound, C18H21N5, is very similar to that observed in other diaryldiazepine structures such as clozapine and clozapine dihydrobromide. N-H...H hydrogen-bond interactions result in the formation of a dimer.
