실험 절차

18.3 g of p-hydroxybenzaldehyde is dissolved in 200 ml of methyl ethyl ketone, and then 22.8 g of potassium carbonate and 24.2 g of m-chlorobenzyl chloride are added thereto. The resulting mixture is refluxed for 8 hours in a stream of nitrogen. Insoluble substances produced are removed by filtration, and then the solvent is distilled away. The resulting residue is distilled under reduced pressure to obtain 32.6 g of 4-(3-chlorobenzyloxy)benzaldehyde in the form of white crystal.
