Reaction Steps

To cooled chlorosulfonic acid (16 ml, −10° C.) was cautiously added D7 (5 g, 0.024 mol) over a period of 2 h. Reaction was allowed to warm to ambient temperature and stirring continued for 3d. The reaction was then poured into ice-water slurry (500 ml), basified using solid potassium carbonate followed by extraction using DCM. Organic phase was separated, dried over MgSO4, filtered and concentrated under reduced pressure to leave an oil. Chromatography on silica gel eluting with ethyl acetate afforded the title compound as yellow oil.
