Procedure

To a solution of the compound of step C (370 mg, 1.01 mmol) in toluene (20 mL) at rt was added PPh3 (397 mg, 1.515 mmol), imidazole (137 mg, 2.02 mmol), and I2 (384 mg, 1.515 mmol). The mixture was stirred for 10 h at 100° C., and quenched with NaHCO3 aqueous solution. The organic layer was diluted with DCM, separated, and the aqueous layer was extracted with DCM. The combined organic layers were dried (MgSO4) and purified by column chromatography (0-100% EtOAc/hex) to give the title compound. LC/MS: [(M+1-56)]+=421
