Procedure

To a suspension of 247 (80 mg, 0.327 mmol) in THF (4 mL), was added PPh3 (258 mg, 0.983 mmol), DEAD (0.155 ml, 0.983 mmol) and isopropanol (0.075 ml, 0.983 mmol), and the reaction mixture was allowed to stir for 48 hours. 3N HCl solution (1.0 mL) was added and the mixture was extracted with DCM. Aqueous phase was collected, neutralized with NaOH 10% (pH ˜11) and extracted with DCM. The organic phase was collected, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified twice by column chromatography: eluents EtOAc/hexane (3:7) and MeOH/DCM (1:20), to afford title compound 248 (19 mg, 31% yield) as yellow solid. MS (m/z): 287.1 (M+1).
