반응 단계
5-methoxy-salicylaldehyde (211.1 mg, 1.39 mmol) and Meldrum's acid (200 mg, 1.39 mmol) were combined in H2O (2 mL). The solution was stirred at 75° C. for 2 h. After cooling to room temperature, the precipitate was filtered and dried at suction to give 241.1 mg of 6-methoxy-3-carboxy-coumarin in a 79% yield.
