Procedure
Trichloroacetyl chloride (2.63 mL, 23.6 mmol) was added dropwise over five minutes to a solution of (2′-methoxy-biphenyl-4-yl)-(5H,11H-pyrrolo[2,1-c][1,4]benzodiazepin-10-yl)-methanone (3.0 g, 7.60 mmol) and N,N-diisopropylethyl amine (2.65 mL, 15.2 mmol) in dichloromethane (60 mL). The reaction was stirred under nitrogen at room temperature overnight and then quenched with water. The organic layer was washed with 0.1N hydrochloric acid and water, dried over anhydrous magnesium sulfate, filtered and concentrated to an oil. The oil was purified by flash chromatography over silica gel Merck-60 using a 0-5% gradient of ethyl acetate in dichloromethane to give the title compound (2.34 g) as a yellow foam.
