To 200 ml of acetone were added 63.5 g of benzyl chloride, 95.15 g of 4-bromophenol, and 69.1 g of potassium carbonate, and the mixture was allowed to react at reflux for 8 hours. After completion of the reaction, the reaction mixture was added into 200 ml of water and extracted with 200 ml of chloroform. The extract was washed with 200 ml of water to obtain a crude product. The crude product was distilled by a Claisen flask to obtain 108.1 g of a distillate, which was further purified by silica gel column chromatography using benzene as an eluent to give 96 g (theoretical yield: 73%) of the entitled compound having a melting point of 47° C.
