Versuchsvorschrift

To a stirred solution of 0.350 g of 2,3-difluorobenzoyl chloride in 5 ml of methylene chloride is added 0.346 ml of triethylamine. After stirring for 3 minutes, 0.500 g of 10,11-dihydro-10-(4-aminobenzoyl)-5H-pyrrolo[2,1-c][1,4]benzodiazepine is added and stirring continued for 72 hours. The reaction mixture is filtered and the solid washed with methylene chloride. The solid is saved. The combined filtrate is washed with water, 2N citric acid, 1M NaHCO3, and brine. The reaction mixture is dried with Na2SO4, filtered and evaporated in vacuo to give 100 mg of a solid. The two solids are combined and dried to afford 790 mg of the desired product as a solid, m.p. 252°-258° C.
