Title: Method for producing carboxylic acid amide

Abstract: A carboxamide can be produced in a high yield by a method for producing a carboxamide, for example, represented by formula (4): ##STR00001## (wherein R.sup.1 and R.sup.3 are as defined below), the method comprising a step of allowing a carboxylic acid ester represented by formula (1): ##STR00002## (wherein R.sup.1 represents an optionally substituented C.sub.1-C.sub.20 hydrocarbon group or an optionally substituented C.sub.3-C.sub.20 heterocyclic group, and R.sup.2 represents an optionally substituented C.sub.1-C.sub.20 hydrocarbon group), an amine represented by formula (2): R.sup.3--NH.sub.2 (2) (wherein R.sup.3 represents a hydrogen atom or an optionally substituented C.sub.1-C.sub.20 hydrocarbon group), and a formamide compound represented by formula (3): ##STR00003## (wherein R.sup.3 is as defined above) to react in the presence of a metal alkoxide.
