Procedure

To a solution of the alcohol from Step B (135 mg, 0.29 mmol) in CH2Cl2, (1.0 ml), DMSO, (1.0 ml) and Et3N (0.2 ml) at room temperature under argon was added pyridine-SO3 complex (185 mg, 1.17 mmol). The mixture was stirred for 3 hrs and then poured into brine, and extracted with EtOAc. The organic extracts were combined, washed with brine, dried (MgSO4) and concentrated in vacuo to give the title compound as an oil.
