Procedure

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 (75 mg, 0.150 mmol), 5-(tributylstannyl)-3-vinylisothiazole (90 mg, 0.225 mmol) and tetrakis(triphenylphosphine)palladium(0) (87 mg, 0.075 mmol) in toluene (4.0 mL) was heated to 120° C. for 45 minutes via microwave irradiation. The reaction mixture was poured into water and was extracted with EtOAc. The extracts were dried over Na2SO4 and concentrated in vacuo. The residue was purified by silica gel chromatography (Flash 60 column) eluting with hexane/EtOAc (1:1) to give the title compound as a yellow solid (59.2 mg, 69%). ESI-MS m/z [M+H]+ calc'd for C27H34FN5O6S, 576. found, 576.
