Procedure

To a solution of 3-hydroxybenzoic acid (6.9 g, 50 mmole) in DMF (100 ml) was added potassium-tert.-butoxide (6.17 g, 55 mmole) and the mixture was stirred at room temperature for one hour. 4-Methoxybenzyl chloride (9.4 g, 60 mmole) was added and the mixture was stirred for 16 hours at 60° C. The mixture was evaporated under reduced pressure and ethyl acetate (250 ml) were added. The organic phase was washed five times with water, dried with sodium sulfate and evaporated under reduced pressure. The product was isolated by silica gel column chromatography with toluene/acetone. Yield: 10.5 g=81%
