A solution of tert-butyl (3R,4R)-4-(4-chloro-2-(2,4-dimethoxybenzyl)-7-fluoro-3-oxo-2,3-dihydro-1H-pyrrolo[3,4-c]pyridin-6-ylamino)tetrahydro-2H-pyran-3-ylcarbamate (51 mg, 0.093 mmol), 4,4,5,5-tetramethyl-2-(5-methylthiophen-2-yl)-1,3,2-dioxaborolane (104 mg, 0.463 mmol), and bis(triphenylphosphine)palladium chloride (65.0 mg, 0.093 mmol) in dioxane (1 mL) and saturated Na2CO3 aq (1 mL) was heated to 140° C. for 40 min. After filtering out the solids, the solvent was removed from the filtrate. The resulting residue was dissolved in MeOH and DCM (10 mL) and was purified via preparative HPLC eluting with water (0.05% TFA) and ACN (80%, 0.035% TFA). The collected fractions were combined and solvent was stripped to dryness via rotary evaporation to give the title compound (31 mg, 55%). [M+H] calc'd for C31H37FN4O6S, 613; found, 613.
