Procedure

To a solution of 1.0 g of 10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine and 10 ml of triethylamine in 50 ml of dichloromethane under argon is added 3.2 g of 6-iodopyridine-3-carbonyl chloride. The mixture is stirred at room temperature for 16 hours and then poured into 100 ml of water. The organic layer is separated and washed with 2% HCl, water, saturated NaHCO3 and dried (Na2SO4). The solvent is removed under vacuum and the residue chromatographed on silica gel with ethyl acetate-hexane as solvent to give the product as a solid.
