実験手順

A stirred solution of the 2′-chloro-2-chloro-5-methoxy-[1,1′-biphenyl]-4-carboxylic acid of Step A (3.09 g, 10.46 mmol) in tetrahydrofuran (20 mL) containing a catalytic amount of N,N-dimethylformamide was treated dropwise with thionyl chloride (1.36 g, 11.51 mmol). The reaction mixture was stirred for 2 hours, and then added dropwise to a solution of 10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine (1.92 g 10.46 mmol) in tetrahydrofuran (20 mL) containing triethylamine (2.32 g, 23 mmol). The reaction mixture was stirred for 2 hours, diluted with dichloromethane and washed with saturated aqueous sodium bicarbonate and brine. The organic layer was dried over anhydrous magnesium sulfate, filtered, and evaporated to dryness. Trituration of the residue with ethyl acetate gave the title compound (1.93 g) which was recrystallized from ethyl acetate/hexanes as white crystals, m.p. 209-211° C.;
