実験手順
1-(10,11-Dihydro-5H-dibenzo[b,e][1,4]diazepin-10-yl)-2,2,2-trifluoroethanone of Step A (3.12 g) was added to dry N,N-dimethylformamide (50 mL) containing sodium hydride (60% dispersion in oil, 0.60 g, washed with hexane). After a short while iodomethane was added (2.0 g) and the mixture stirred overnight at room temperature, quenched with ice and diluted with brine. The precipitate was collected and redissolved in dichloromethane. The solution was dried over anhydrous sodium sulfate and filtered through a short column of Magnesol® which was eluted with several additional volumes of dichloromethane. The total effluent was evaporated to dryness and the residue crystallized from hexane to provide the title compound as colorless crystals (1.23 g), m.p. 104–106° C.
