実験手順
To a stirred mixture of salicylamide (6.85 g, 50 mmol) and 4-[2-oxo-propoxy]nitrobenzene (9.75 g, 50 mmol) in benzene (500 mL) was added piperidine (0.52 mL, 5 mmol). The reaction mixture was immersed in a pre-heated oil bath (˜100° C.) and refluxed for 10 h with continuous removal of water using Dean-Stark water separator. The reaction mixture was cooled to room temperature End the precipitated brown coloured solid was filtered, washed with benzene and dried to afford the title compound (13.5 g, 86%).
