Procedure

A solution of Intermediate 153g (317 mg, 0.31 mmol) in MeOH (3.1 mL) was treated with pyridinium para-toluenesulfonate (235 mg, 0.93 mmol) and the mixture was stirred at 45° C. for 19 h. The cooled solution was concentrated in vacuo, and the residue was partitioned between DCM and a saturated aqueous sodium bicarbonate solution. The phases were separated and the aqueous layer was extracted with DCM (×2). The combined organic phase was washed with water, a saturated aqueous sodium bicarbonate solution, and brine, dried (Na2SO4) and concentrated in vacuo to a cream coloured foam. The foam was purified by FCC, using 0-10% MeOH in DCM, to give the title compound as a colourless glass (217 mg, 75%). LCMS (Method 3): Rt 5.06 min, m/z 933.7 [MH+].
