Procedure
A mixture of 1,3-bis-(p-methoxyphenyl)cyclobutane (13.57 g., 0.051 mole) and pyridine hydrochloride (46.8 g., 0.41 mole) is heated at 210° C. under a nitrogen atmosphere for 30 minutes and then poured into 500 ml. of water. Several ethyl acetate extracts are taken, combined, washed (dilute HC1, water), dried (MgSO4), and evaporated. The desired product after recrystallization from benzene weighs 8.1 g. (67%), m.p. 148°-163.5° C.
