Reaction Steps

A mixture of 2-(3-methoxyphenyl)-5-phenylpentane (18.4 g.) and pyridine hydrochloride (94 g. ) under nitrogen is heated to 190° C. for 2 hours with vigorous stirring. The reaction mixture is cooled, dissolved in 6 N hydrochloric acid (200 ml.) and diluted with water to 600 ml. The aqueous solution is extracted with ethyl acetate (4×100 ml. ), the ethyl acetate extracts dried over sodium sulfate and concentrated under vacuum to yield the crude product. The product is purified by silica gel chromatography.
