The mixture was cooled to 0° C. and 1,1-dichloromethyl methyl ether (0.50 mL, 5.53 mmol) was added and the reaction was allowed to warm to room temperature. After 20 hours, the reaction was quenched with sodium bicarbonate. The aqueous phase was extracted with ethyl acetate, dried over magnesium sulfate, filtered and the solvent removed to yield 730 mg (100%) of a brown solid.
