実験手順

A mixture of 5-Hydroxy-6-indan-1-one, Intermediate H, (0.50 g, 0.0028 mol), 4-chloromethyl-2,2-dimethyl-1,3-dioxolane (0.766 mL, 0.0056 mol), potassium carbonate (1.54 g, 0.011 mol) and DMF (20.0 mL) was stirred at 95° C. for 3 days. Water (150.0 mL) was added and the mixture was extracted with ethyl acetate (2×150 mL). The organic layer was washed with sat. NaHCO3, brine and dried over Na2SO4. The solvent was then removed in vacuo to yield 5-(2,2-dimethyl-[1,3]dioxolan-4-ylmethoxy)-6-methoxy-indan-1-one (Intermediate I) as light brown solid. MS m/z 293 (M+H)+.
