A solution of ethyl 2-hydroxy-6-methylbenzoic acid (4.56 g, 25.3 mmol) and diisopropylethylamine (13.2 ml, 76 mmol) in dry dichloromethane (30 ml) was cooled in an ice-bath. Chloromethyl methyl ether (3.83 ml, 50.6 mmol) was added slowly and the mixture was allowed stand at 0° C., warning slowly to room temperature. After 36 h a further portion of chloromethyl methyl ether (1.9 ml) was added and the mixture was left at room temperature overnight. The mixture was then washed with 10% citric acid, water and brine, dried and evaporated to give the title compound (6.34 g, 100%).
