Procedure

The crude product of (S)-(+)-4-(4-methoxybenzyloxymethyl)-2,2-dimethyl-1,3-dioxolane (4.1 g) was dissolved in methanol (10 mL) and the solution was added with 1N hydrochloric acid and stirred at room temperature for one day. The solution was adjusted to pH6 by addition of saturated aqueous sodium hydrogen carbonate, and extracted four times with dichloromethane. After the organic layer was dried over anhydrous sodium sulfate, the solvent was removed. The residue was purified by silica gel column chromatography to obtain (R)-(+)-3-(4-methoxybenzyloxy)-1,2-propandiol (2.4 g, 69%).
