The reaction mixture was stirred at 0° C. for 15 min. The resulting mixture was poured into water and then the THF was evaporated. The aqueous layer was then extracted with ethyl acetate and the combined organic extracts washed with brine, dried over sodium sulphate, filtered and evaporated. Purification by chromatography (silica, 0 to 100% ethyl acetate in heptane) afforded the title compound (410 mg, 90%) as an off white solid. MS: m/e=208.0 [M+H]+.
