The present invention provides a novel method for preparing an amide derivative. The method of the present invention enables to economically prepare various amide derivatives containing pranlukart by reacting a carboxylic acid derivative 5 and an amine derivative through a brief procedure compared with a conventional technology, and permits to obtain a final product at a high yield rate because it is feasible to eliminate by-products after termination of reactions. Accordingly, the present method is to be quite suitable for massive production.
本发明提供了一种制备酰胺衍生物的新方法。与传统技术相比,本发明的方法通过简短的程序,使得可以经济地制备含有普兰卢卡特的各种酰胺衍生物,通过反应羧酸衍生物5和胺衍生物,因为在反应终止后可以消除副产物,从而可以以高产率获得最终产品。因此,本方法非常适合大规模生产。
