2-Hydroxy-5-methylbenzoic acid methyl ester (4.98 g, 30 mmol) and 1-chloromethyl-4-methoxybenzene (4.69 g, 30 mmol) and K2CO3 (4.55 g, 33 mmol) in DMF (50 mL) is heated to 60° C. for 72 h. The mixture is then diluted with EtOAc (100 mL), and then washed with 1N HCl solution and brine. It is then dried and concentrated. The residue is purified by flash chromatography to give the title compound as a colorless oil.
