METHODS FOR PREPARING AMIDE DERIVATIVES

摘要

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.
