Procedure
A mixture composed of 15 g of 4-benzyloxybenzyl chloride and 15 g of 4-aminophenol was refluxed in 200 ml of N,N-dimethylformamide for 30 minutes. After water was added to the reaction mixture, the product was extracted with ethylacetate. The organic layer was washed with water and dried over anhydrous sodium sulfate. After the solvent was distilled off, the resulting crude product was purified by silica gel column chromatography (using a 50:1 mixture of chloroform and acetone as the eluent) to obtain 11 g of 4[-N-(4-benzyloxybenzyl)-amino]phenol.
