Procedure

To a solution of Intermediate 85h (1.37 g, 2.08 mmol), Ph3P (1.09 g, 4.16 mmol) and Et3N (840 mg, 8.32 mmol) in THF (60 mL) was added hexachloroethane (980 mg, 4.16 mmol) and the mixture stirred at RT for 20 h. The mixture was diluted with DCM, washed with 10% aq. K2CO3 solution, brine, dried (MgSO4) and concentrated in vacuo. The residue was purified by FCC, using 0-100% EtOAc in cyclohexane, to give the title compound as a clear oil (350 mg, 41%). LCMS (Method 4): Rt 3.07 min, m/z 407 [MH+].
