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 Example 4, Step B (0.760 g, 1.89 mmol), 3,4-dihydro-naphthalen-1-yltrifluoromethanesulfonate (0.579 g, 2.08 mmol) and dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium (II) dichloromethane adduct (0.0460 g, 0.0567 mmol) were combined in N,N-dimethylformamide (9.5 mL). Aqueous sodium carbonate (2M, 4.73 mL, 9.45 mmol) was added and the was heated to 60° C. for 3 hours. After cooling to room temperature, the mixture was diluted with ethyl acetate and washed with water and brine. The organic phase was dried over anhydrous magnesium sulfate, filtered and concentrated and the residue purified by flash column chromatography on silica gel eluting with 30% ethyl acetate in hexane. Recrystallization from hexane afforded 0.740 g of the title compound as white crystals, m.p.108° C.
