Procedure

To a solution of 0.75 g of 10-[[6-[2- (dimethylamino) ethylamino]-3-pyridinyl]carbonyl]-10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine and 5 ml of diisopropylethylamine in 75 ml of dichloromethane is added (slowly) 0.35 g of 5-fluoro-2-methylbenzoyl chloride in 10 ml of dichloromethane. The mixture is stirred at room temperature for 16 hours and the solution washed well with water. The organic layer is dried (MgSO4) and the solvent removed under vacuum. The residue is purified by column chromatography on silica gel with 30% methanol in chloroform as eluent to give 0.80 g of yellow solid; mass spectrum (CI), 511 (M+1).
