Reaction Steps

α-trichloromethyl-p-methoxybenzyl alcohol, 5.0g, and p-methoxyphenol, 2.48g, were added to a mixture of phosphorus pentoxide, 18g, and phosphoric acid, 12 ml, and heated for 1 hr. on the steam bath. After standing overnight, ice was added and the mixture extracted with ether. The product was purified by column chromatography on silica gel and eluted with 5% ether in petroleum ether (60°-68°C) to give α-trichloromethyl-p-methoxybenzyl p-methoxyphenyl ether, mp 90°C. This method of synthesis is referred to in Table I as method B.
