Reaction Steps

To a stirring solution of 4-(2-Hydroxy-3,4-dimethoxy-phenyl)-indan-1-one (Compound 303) (100 mg, 0.352 mmol) in acetonitrile (15 mL), were added potassium carbonate (145 mg, 1.056 mmol) and 3-(bromomethyl)-3-(methoxymethyl)oxetane (102 mg, 0.528 mmol) and the resultant reaction mixture was heated to 70° C. for 16 h. The reaction mixture was diluted with water and extracted with ethyl acetate (3×). The combined ethyl acetate layer was washed with brine and dried over anhydrous sodium sulphate and concentrated under reduced pressure. Purification by column chromatography (silica gel, 0-25% ethyl acetate in pet ether) to afforded the title compound as a colorless liquid.
