Reaction Steps

To a stirred suspension of 3-hydroxyphthalic acid dimethyl ester (1.1 g, 5.2 mmol) in acetone (45 mL) and potassium carbonate (2.2 g, 15.7 mmol), was added 1-bromomethyl-4-methoxy-benzene (0.79 mL, 5.5 mmol). The mixture was refluxed for six hours. The solvent was evaporated in vacuo, and the residue was partitioned between water (50 mL) and ethyl acetate (80 mL). The organic layer was washed with water (2×50 mL), dried, concentrated in vacuo, and purified by flash column chromatography (Silica Gel, EtOAc/Hexane, 0% gradient to 100% 30 min) to give 3-(4-methoxy-benzyloxy)-phthalic acid dimethyl ester (2.0 g, 115% crude yield). The product was used in the next step without further purification.
