Procedure

A solution of 4-hydroxy-3-(4-methoxyphenyl)benzyl alcohol (5.54 g, 24 mmol) in acetone (250 mL) was treated with MnO2 and the mixture stirred for 3 days. The solid was filtered on diatomaceous earth and the filtrate was concentrated under reduced pressure to afford 5.96 g of title compound as a pale green oil, impure with manganese salts.
