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 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 washed sequentially with water, saturated aqueous sodium bicarbonate, 0.5 N hydrochloric acid and water. The dichloromethane solution was dried over anhydrous sodium sulfate, filtered, then evaporated in vacuo to dryness to yield an off-white foam. Purification by flash chromatography on silica gel eluting with hexane-ethyl acetate (2:1) resulted in a white foam (3.02 g), m.p. 77-80° C., MS m/z: 400 (M)+.
