実験手順

25.2 g (86 mmol) 5-acetyl-8-benzyloxy-1H-quinolin-2-one (European Journal of Medicianl Chemistry 1984, 19(4), 341) and 50 g (142 mmol) benzyltrimethylammonium dichloriodate in 500 mL dichloroethane and 300 mL methanol are stirred overnight at reflux temperature. The reaction mixture is evaporated down and the residue is stirred overnight in THF and 1 N hydrochloric acid. After the THF has been distilled off the precipitated solid is suction filtered, washed with diethyl ether and dried.
