The reaction mixture was cooled to room temperature and the gas was released. 120 ml of benzene was charged in the autoclave to dissolve an oil layer. An insoluble matter was filtered out. After washing with 30 ml of benzene, a resulting mother wash solution was shaken well and then left to stand to obtain a benzene layer. The benzene layer was washed with 120 ml of water three times and then separated from water. Benzene was distilled off under reduced pressure to obtain an oily product. According to gas chromatographic analysis by the internal standard method, the product contained 98.5% of 3-phenoxybenzyl 2-(4-ethoxyphenyl)-2-methylpropyl ether and 0.5% of unreacted 3-phenoxybenzyl 2-(3-chloro-4-ethoxyphenyl)-2-methylpropyl ether. The amounts of 3-phenoxytoluene and 4-ethoxyneophyl alcohol formed by ether bond cleavage were each less than 0.2%.
