Procedure

(10,11-Dihydro-5H-pyrrolo [2,1-c][1,4]benzodiazepin-10-yl)-[3-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-methanone of Step B (3.50 g, 8.17 mmol), cyclohex-1-en-1-yl trifluoromethanesulfonate (2.26 g, 9.80 mmol) and dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium (II) dichloromethane adduct (0.200 g, 0.245 mmol) were combined in N,N-dimethylformamide (40.9 mL). Aqueous sodium carbonate (2 M, 20.5 mL, 40.9 mmol) was added and the reaction heated to 60° C. overnight. After cooling to room temperature, the reaction mixture was diluted with ethyl acetate and the organic layer washed with water and brine. The organic phase was dried over anhydrous magnesium sulfate, filtered and concentrated. The residue was dissolved in hot ethyl acetate/petroleum ether (1:1) and filtered. The filtrate was concentrated and the residue recrystallized from petroleum ether to afford 2.52 g of the title compound as light brown crystals, m.p. 182-183° C.
