Procedure

(10,11-Dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepin-10-yl)-[5-chloro-2-methoxy-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-methanone of Step E (0.220 g, 0.459 mmol), cyclohex-1-en-1-yl trifluoromethanesulfonate (0.116 g, 0.505 mmol) and dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium(II) dichloromethane adduct (0.011 g, 0.014 mmol) were combined in N,N-dimethylformamide (2.3 mL). 2 M aqueous sodium carbonate (1.15 mL, 2.30 mmol) was added and the reaction heated to 60° C. for 2 hours. After cooling to room temperature, the reaction mixture was diluted ethyl acetate and washed with water and brine. The organic phase was dried over anhydrous magnesium sulfate, filtered and concentrated. Flash column chromatography on silica gel eluting with a solvent gradient from 30 to 40% ethyl acetate in hexane afforded the title compound (0.140 g) as an oil. The oil was dissolved in diethyl ether/petroleum ether and concentrated to afford an amorphous white solid.
