7-氨基-4-甲基香豆素的合成

The Synthesis of 7Amino4methylcoumarin

以间氨基苯酚和乙酰乙酸乙酯为原料，在浓硫酸存在下，进行Ｐｅｃｈｍａｎｎ缩合反应，生成荧光物质———７氨基４甲基香豆素，并采用正交设计法，进行最佳工艺条件优选，总得率超过文献产率。

This paper reports an improved synthetic method of 7amino4methylcoumarin with Pechmann condensation reaction,the results showed that product yielded was over literature record.
