実験手順

To an ice cold solution of Intermediate 18a (980 mg, 2.97 mmol) in THF (15 mL) was added triphenylphosphine (1.56 g, 5.94 mmol), triethylamine (1.65 mL, 11.9 mmol) and hexachloroethane (1.40 g, 5.94 mmol). The reaction was stirred for 90 min then partitioned between EtOAc (75 mL) and water (75 mL) and the aqueous layer extracted with EtOAc (3×). The combined organic layers were washed with brine, dried (MgSO4), filtered and evaporated in vacuo then purified by SCX-2, washing with MeOH and eluting with 2M NH3 in MeOH to give the title compound (640 mg, 2.05 mmol, 69%). LCMS (Method 2): Rt 0.28, 1.32, m/z 313 [MH+].
