Procedure

A solution of 6.2 g of α-[4-(benzyloxy)-3-methoxyphenyl]-3-quinolinemethanol in 200 ml of methylene chloride is treated with 62 g of manganese dioxide and stirred at the reflux temperature 2 hours. After cooling the precipitate is filtered under suction and washed with methylene chloride. The filtrate is evaporated and the oil obtained is dissolved in hot ether, whereupon the solution is treated with a small amount of pentane. The separated crystals are filtered under suction. There is obtained 4-(benzyloxy)-3-methoxyphenyl (3-quinolinyl) ketone in the form of colorless crystals of m.p. 110°-111°.
