Procedure

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 (80 mg, 0.160 mmol), 5-(tributylstannyl)-3-vinylisothiazole (96 mg, 0.240 mmol), and tetrakis(triphenylphosphine)palladium(0) (93 mg, 0.080 mmol) in toluene (4.0 mL) was heated to 120° C. for 45 minutes via microwave irradiation. The reaction mixture was subsequently poured into water and was extracted with EtOAc. The extracts were dried over Na2SO4 and were 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, which was used without further purification (81.3 mg, 88%). ESI-MS m/z [M+H]+ calc'd for C28H36FN5O5S, 574. found, 574.
