A solution of tert-butyl 6-((1R,2S)-2-(tert-butoxycarbonylamino)cyclohexylamino)-4-chloro-7-fluoro-3-oxo-1H-pyrrolo[3,4-c]pyridine-2(3H)-carboxylate (200 mg, 0.401 mmol), 2-(tributylstannyl)thieno[2,3-b]pyridine (340 mg, 0.802 mmol) and tetrakis(triphenylphosphine)palladium(0) (463 mg, 0.401 mmol) in toluene (3 mL) was heated to 102° C. overnight. The reaction mixture was diluted with EtOAc (50 mL) and saturated aqueous NaHCO3 (100 mL). The organic layer was separated and the aqueous layer was washed with EtOAc (50 mL). The organic layers were combined, dried over Na2SO4, and the solvent was removed in vacuo. The crude product was purified by silica gel column chromatography, eluting with a gradient of 5-50% EtOAc and hexane over a period of 120 minutes. The fractions were collected to give the title compound (85 mg, 35%). ESI-MS m/z [M+H]+ calc'd for C30H36FN5O5S, 598. found, 598.
