Procedure
24.2 g (0.2 mol) of 3-hydroxybenzaldehyde and 25.32 g (0.2 mol) of benzyl chloride were placed in 500 ml of acetone and 21.2 g (0.2 mol) of sodium carbonate was added thereto. The resulting solution was stirred for 12 to 24 hours with heating, cooled to room temperature. The solvent was removed under a reduced pressure and the residue thus obtained was washed with water and the extracted with ethyl acetate twice. The organic layer was dried and the solvent was removed under a reduced pressure to obtain a residue. The residue was subjected to column chromatography using a mixture of n-hexane and ethyl acetate (9:1) as an eluent to obtain 35.6 g (yield 84%) of the title compound as a colorless liquid.
