30 g (0.102 mole) 4-(methylsulfonyloxy)phenethyl methanesulfonate was dissolved in acetonitrile and slowly added to a mixture of 31.1 g (0.255 mole) p-hydroxybenzaldehyde and 41.46 g (0.3 mole) potassium carbonate in acetonitrile and refluxed until the starting material was consumed. The salt was filtered off, the solvent evaporated in vacuo, dichloromethane was added and the organic phase was washed with water. After evaporation of the solvent, purification by chromatography on silica gel using dichloromethane as eluent gave 21.6 g (yield 66%) of 4-[2-(4-formylphenoxy)ethyl]phenyl methanesulfonate.
