Procedure

60% sodium hydride (992 mg) was added to a solution of 1,1-dimethoxy-propan-2-ol (2.49 g) in dimethylformamide (50 mL) at 0° C., followed by stirring for 15 minutes. Allyl bromide (1.96 mL) was added at the same temperature, followed by stirring for 15 minutes. Ice was added to the reaction solution, followed by extraction with ethyl acetate. The organic layer was concentrated under reduced pressure. The residue was purified by silica gel column chromatography to obtain the title compound (3.46 g).
