Versuchsvorschrift

To a stirred solution of the 2-chloro-2′-ethoxy-5-methoxy[1,1′-biphenyl]-4-carboxylic acid of Step A (0.491 g) in tetrahydrofuran (5 mL) containing a catalytic amount of N,N-dimethylformamide was added dropwise thionyl chloride (0.210 g, 1.76 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 (0.294 g, 1.60 mmol) in tetrahydrofuran (5 mL) containing triethylamine (0.357 g, 3.52 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 methanol provided the title compound as an off-white solid, 99.24% pure by analytical HPLC [Primesphere C-18 column (2.0×150 mm); mobile phase 70/30 acetonitrile/water containing 0.1% phosphoric acid], m.p. 213-215° C.
