Reaction Steps

Sodium hydride (0.8 g) was added with DMF (5 mL) and tetrahydrofuran (THF, 20 mL), and the solution was stirred at 0° C. The solution was added dropwise with a solution of (S)-(+)-2,2-dimethyl-1,3-dioxolan-4-methanol (2.4 g) in mixture of DMF (3 mL) and THF (3 mL), and stirred at 0° C. for one hour. The solution was added with 4-methoxybenzyl chloride (2.8 mL) and stirred at room temperature for three hours. The solution was added with saturated ammonium chloride solution, and extracted twice with ethyl acetate. The resulting organic layer was washed four times with water, once with saturated brine. After the organic layer was dried over anhydrous magnesium sulfate, and the solvent was removed to obtain a crude product of (S)-(+)-4-(4-methoxybenzyloxymethyl)-2,2-dimethyl-1,3-dioxolane (4.1 g, 89%).
