Procedure

A mixture of tert-butyl (1S,2R)-2-(4-chloro-2-(2,4-dimethoxybenzyl)-7-fluoro-3-oxo-2,3-dihydro-1H-pyrrolo[3,4-c]pyridin-6-ylamino)cyclohexylcarbamate (65 mg, 0.118 mmol), aqueous sodium carbonate (2 N, 0.237 mL, 0.474 mmol), 2-(benzofuran-3-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (43 mg, 0.178 mmol) and bis(triphenylphosphine)palladium chloride (17 mg, 0.024 mmol) in DME (2 mL) was placed in a vial. The vial was purged with nitrogen, sealed, and the reaction mixture heated at 120° C. for 1 h. The mixture was filtered through a pad of Celite, which was rinsed with MeOH. The solvent was removed in vacuo and the residue diluted with MeOH, passed through a microfiltration frit, and purified via preparative HPLC. The fractions were collected and concentrated in vacuo to give the title compound as a tan oil (36.3 mg, 48%). [M+H] calc'd for C35H39FN4O6, 632; found, 632.
