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 (114 mg, 0.245 mmol), 5-cyanothiophen-2-ylboronic acid (113 mg, 0.736 mmol), tris(dibenzylideneacetone)di-palladium(0) (13.47 mg, 0.015 mmol), and 2-(dicyclohexylphosphino)biphenyl (5.16 mg, 0.015 mmol) in dioxane (2 mL) and DMF (0.5 mL) was heated to 160° C. under microwave irradiation for 45 min. UPLC showed 50% conversion. The reaction mixture was subsequently heated at 160° C. under microwave irradiation for 45 min. Additional 5-cyanothiophen-2-ylboronic acid (113 mg, 0.736 mmol) was added and the reaction mixture was heated at 160° C. under microwave irradiation for 60 min. After removal of the solvent, the resulting crude material was reconstituted in MeOH/DMF (6.0 mL) and purified via preparative HPLC eluting with water (0.05% TFA) and ACN (40-80% gradient, 0.035% TFA). The collected fractions were stripped to dryness via rotary evaporation to yield the title compound. [M+H] calc'd for C27H28FN5O4S, 538; found, 538.
