Procedure

A mixture of 2-(3-methoxyphenyl)propyl 2-phenylethyl ether (176 mg., 0.65 mmole), pyridine (0.4 ml., 4.96 mmole) and dry pyridine hydrochloride (4 g., 34.6 mmole) is heated at 190° C. for 6 hours. The reaction mixture is cooled and added to a mixture of water (100 ml.) and ether (150 ml.). The ether extract is washed once with water (50 ml.) and, along with a second ether extract (50 ml.) of aqueous phase, is dried over magnesium sulfate and evaporated to an oil. The oil is purified via preparation layer chromatography on silica gel plates, eluted six times with 30% ether-pentane to yield the title product.
