A solution of tert-butyl 6-((3R,4R)-3-(tert-butoxycarbonylamino)tetrahydro-2H-pyran-4-ylamino)-4-chloro-7-fluoro-3-oxo-1H-pyrrolo[3,4-c]pyridine-2(3H)-carboxylate (10 mg, 0.02 mmol), 3-methyl-5-(tributylstannyl)isothiazole (23.25 mg, 0.06 mmol) and tetrakis(triphenylphosphine)palladium(0) (23.07 mg, 0.02 mmol) in toluene (3 mL) was heated to 120° C. for 45 min under microwave irradiation. The reaction mixture was poured into water and extracted with EtOAc. The organic extracts were dried over anhydrous Na2SO4, filtered, and evaporated in vacuo. After removal of solvent, the resulting crude material was reconstituted in DMF and purified via preparative HPLC eluting with water (0.05% TFA) and ACN (55-80% gradient, 0.035% TFA). The collected fractions were combined and ACN was removed via rotary evaporation. The resulting aq solution was neutralized with saturated aq NaHCO3 and washed with EtOAc (2×50 mL), dried over anhydrous Na2SO4, filtered, and the organic phase stripped to dryness via rotary evaporation to give the title compound. [M+H] calc'd for C26H34FN5O6S, 564; found, 564.
