실험 절차

To a mixture of 10,11-dihydro-5H-pyrrolo [2,1-c][1,4] benzodiazepine (1.44 g) and triethylamine (0.95 g) in dichloromethane (40 mL) cooled in an ice bath, was added dropwise a solution of the crude 4-bromo-2-chlorobenzoyl chloride (2.42 g) in dichloromethane (20 mL). The cooling bath was removed and after stirring for 22 hours, the reaction mixture was sequentially washed with water, saturated aqueous sodium bicarbonate, 0.5 N hydrochloric acid and water. The dichloromethane solution was dried over anhydrous sodium sulfate, filtered and then evaporated to dryness to yield an off-white foam. Purification by flash chromatography on silica gel Merck-60 eluting with hexane-ethyl acetate (2:1) resulted in a white solid (3.02 g), m.p. 77-80° C.
