Procedure
The 4-(3-methylpyrazol-1-yl)benzoyl chloride was added to an ice-cooled solution of 10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine (0.55 g) and diisopropylethylamine (0.44 g) in dichloromethane (25 ml). After stirring at room temperature for 18 hours, the reaction mixture was washed with water and a saturated aqueous sodium bicarbonate solution. The dichloromethane solution was dried over anhydrous sodium sulfate and filtered through a short column of hydrous sodium magnesium silicate and further eluted with several volumes of dichloromethane. The combined organic phase was concentrated on a hot plate with the gradual addition of hexane until crystallization occurred. After cooling, the title compound (0.90 g) was obtained as an amorphous solid, MS, m/z: 369 (M+H)+.
