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 (50 mg, 0.1 mmol), tributyl(thiophen-2-yl)stannane (44.7 mg, 0.12 mmol) and tetrakis(triphenylphosphine)palladium(0) (115 mg, 0.1 mmol) in toluene (3 mL) was heated to 102° C. for 24 h. The solid was filtered though a pad of Celite, and resulting crude material was reconstituted in MeOH/DCM (20 mL) and purified via preparative HPLC. The collected fractions were combined and stripped to dryness via rotary evaporation to yield the title compound (30 mg, 55%).
