In methanol; at 60 - 80℃; for 3h;Reflux;
General procedure: Condensation of 4-amino-3,5-dimethyl isoxazole (1.1230 g, 1.0 mmol) and 2-hydroxy-3-methoxy benzaldehyde (1.5215 g, 1.0 mmol) in methanol solution reuxed with stirring at60-80 C for 3 h, gave after cooling to room temperature, the dark yellow precipitate whichwas ltered o and washed with petroleum ether. Further recrystallization from methanoland drying in a vacuum desiccator over P4O10 gave the pure product. The reaction progresswas monitored by TLC.
