To a solution of (2,2-Dimethyl-5-oxo-[1,3]dioxolan-4-yl)-acetic acid 4-allyl-2-methoxy-phenyl ester (1.0 g, 3.12 mmol) in THF (10.0 mL) was added 1N hydrochloric acid (10 mL) at room temperature (25° C.) and the mixture was stirred at same temperature over a period of 6 h. The solvent was evaporated to half volume, saturated with sodium chloride and the product was extracted with ethyl acetate (2×100 mL). The organic layer was dried over sodium sulphate and concentrated to obtain off-white solid (0.81 g, 93%).
