Procedure
Hexachloroethane (990 mg, 4.18 mmol) was added portionwise to a solution of Intermediate 4a (707 mg, 2.09 mmol), triphenylphosphine (1.103 g, 4.18 mmol) and triethylamine (1.2 mL, 8.36 mmol) in dry THF (30 mL) at RT. The mixture was stirred for 2 h. The resulting precipitate was filtered off and the filtrate evaporated. The residue was purified by SCX-2, eluting with MeOH followed by 2M NH3 in MeOH, to give a pale orange coloured solid. This was triturated (diethyl ether) to give the title compound as a buff-coloured solid (540 mg, 80%). LCMS (Method 1): Rt 2.79 min, m/z 321 and 221(-Boc) [MH+].
