Procedure

To a stirred solution of 0.320 g of 2,3-dimethylbenzoyl chloride in 10 ml of methylene chloride is added 0.33 ml of triethylamine. After stirring for 15 minutes, 0.485 g of 10,11-dihydro-10-(4-aminobenzoyl)-5H-pyrrolo[2,1-c][1,4]benzodiazepine is added and stirring continued for 5 hours. The reaction mixture is washed with water, 1N HCl, NaHCO3, and brine. The reaction mixture is dried with Na2SO4, filtered and evaporated in vacuo to give a solid which is purified by flash chromatography using 1:1 ethyl acetate-hexane to give 0.39 g of solid, m.p. 168°-170° C.
