Dimethyl Sulfoxide → N-[(5-Bromopyridin-3-yl)methyl]-10-[(2'-methoxy-1,1'-biphenyl-4-yl)carbonyl]-10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine-3-carboxamide

A solution of 2,2,2-trichloro-1-{10-[(2′-methoxy-1,1′-biphenyl-4-yl)carbonyl]-10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepin-3-yl}ethanone (0.288 g, 0.534 mmol), (5-bromopyridin-3-yl)methylamine of Step C (0.20 g, 1.07 mmol), triethylamine (0.043 g, 0.588 mmol), dimethylsulfoxide (0.190 mL, 2.67 mmol), and acetonitrile (5 mL) was heated for 17 hours at an oil bath temperature of 81° C. The solvent was removed under reduced pressure and the resulting residue taken up in dichloromethane. The organics were washed with water and brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to a yellow solid. The solid was triturated with hexane, diethyl ether, and ethyl acetate, collected by filtration, and dried under reduced pressure to give the title compound (0.145 g) as an off white solid, m.p 180-184° C.
