Procedure

To a solution of Intermediate 80a (260 mg, 0.98 mmol), Ph3P (511 mg, 1.95 mmol) and Et3N (544 μL, 3.91 mmol) in THF (10.0 mL) at 0° C. was added hexachloroethane (462 mg, 1.95 mmol). The reaction was stirred at RT overnight then partitioned between EtOAc and water. The aqueous layer was then extracted with EtOAc (3×). The combined organic layers were washed with brine, dried (MgSO4), filtered and evaporated in vacuo. The residue was taken up in MeOH and loaded onto an SCX-2 cartridge, which was washed with MeOH and eluted with 2M NH3 in MeOH. The reaction showed 50% conversion so was re-submitted to the reaction conditions overnight at 50° C. The workup and purification procedures were repeated to give the title compound (209 mg, 86%). 1H NMR (300 MHz, CDCl3): 1.64 (6H, s), 1.74-1.82 (4H, m), 2.52-2.57 (4H, m), 7.16 (1H, ddd, J 9.8, 7.4, 2.3), 7.69 (1H, m), 8.93 (1H, ddd, J 4.5, 2.3, 0.7).
