Potassium Carbonate → HCID 66906613, compound

Participants

Reaction Steps

To a stirred suspension of 3-hydroxyphthalic acid dimethyl ester (1.4 g, 6.7 mmol) in acetone (30 mL) and potassium carbonate (2.8 g, 20 mmol) was added 3-fluorobenzyl bromide (0.89 mL, 7.0 mmol) and refluxed overnight. The solvent was evaporated and the residue was partitioned between water (100 mL) and ethyl acetate (50 mL) and washed with water (2×100 mL). The combined organic phases was dried, concentrated and purified by flash column chromatography (EtOAc/Hexane) to give 3-(3-fluoro-benzyloxy)-phthalic acid dimethyl ester (2.4 g, 113% crude yield). The product was used in the next step without further purification.
