실험 절차

Hexachloroethane (426 mg, 1.80 mmol) was added portion-wise to a stirred mixture of Intermediate 56c (410 mg, 0.90 mmol), Ph3P (472 mg, 1.80 mmol) and Et3N (500 μL, 3.60 mmol) in THF (15 mL) at RT. The reaction mixture was stirred for 18 h, then filtered and concentrated in vacuo. The resulting residue was purified by FCC, using 0-25% MeOH in EtOAc, to give the title compound (237 mg, 60%). LCMS (Method 3): Rt 2.95 min, m/z 436 [MH+].
