Procedure

A solution of (R)-2-(4-chloro-2-(2,4-dimethoxybenzyl)-7-fluoro-3-oxo-2,3-dihydro-1H-pyrrolo[3,4-c]pyridin-6-ylamino)-4-methylpentanamide (83 mg, 0.179 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (111 mg, 0.536 mmol), and bis(triphenylphosphine)palladium chloride (12.53 mg, 0.018 mmol) in dioxane (2 mL) and saturated aq Na2CO3 (2 mL) was heated at 120° C. for 30 min. After filtering off the solid, the solvent was removed, and the residue was dissolved in MeOH and DCM and was purified by preparative HPLC. The fractions were collected and the solvent was stripped to dryness via rotary evaporation to yield the title compound (40 mg, 44%). [M+H] calc'd for C26H31FN6O4, 511. found, 511.
