실험 절차

A mixture of 0.40 g of 10,11-dihydro-10-(3-methyl-4-aminobenzoyl)-5H-pyrrolo[2,1-c][1,4]benzodiazepine, 0.40 g of 2,4-dichlorobenzoyl chloride and 0.75 g of diisopropylethylamine in 50 ml of dichloromethane is stirred at room temperature for 16 hours. The mixture is washed with water, dried (MgSO4) and the solution passed through a thin pad of hydrous magnesium silicate. The filtrate is concentrated and hexane added to give crystals. Recrystallization from dichloromethane-hexane gives 0.52 g of crystals, m.p. 213°-215° C.
