Procedure
Intermediate 2a (458 mg, 1.63 mmol) was dissolved in THF (15 mL) and cooled in an ice/water bath. Triphenylphosphine (854 mg, 3.26 mmol) was added followed by triethylamine (907 μL, 6.52 mmol) and hexachloroethane (773 mg, 3.26 mmol). The reaction was stirred for 18 h and then loaded onto an SCX-2 cartridge, which was washed with MeOH and product eluted with 2M NH3 in MeOH. Further purification by FCC, using 0-10% [2M NH3 in MeOH] in DCM, afforded the title compound (310 mg, 1.18 mmol, 72%). LCMS (Method 4): Rt 0.28 min, m/z 264 [MH+].
