実験手順

To a mixture of 10-[(2′-methyl-1,1′-biphenyl-3-yl)carbonyl]-10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine of Step B (1.7 g, 4.5 mmol) and sodium carbonate (0.95 g, 9.0 mmol) in dry tetrahydrofuran (40 mL) was added dropwise trichloroacetyl chloride (0.75 mL, 6.7 mmol) and the reaction mixture stirred at room temperature under nitrogen for 18 hours. The reaction mixture was then diluted with ethyl acetate (150 mL), washed with 1 M hydrochloric acid (150 mL), water (150 mL) and brine (150 mL), dried over anhydrous magnesium sulfate, and concentrated in vacuo to give a dark foam. Purification by flash chromatography using a solvent gradient of 60% to 80% dichloromethane in hexane afforded a white solid that was recrystallized from hot ethyl acetate to give the title compound (1.2 g, 50%) as a white needles.
