Abstract

A method for producing a propargylamine compound represented by the general formula (I): ##STR1## which comprises reacting a propargyl compound represented by the general formula (II): ##STR2## with an aromatic aldehyde represented by the general formula (III): EQU ArCHO (III) and ammonia to obtain an imine compound represented by the general formula (IV): ##STR3## and hydrolyzing the resultant imine compound. It is to provide a method for producing a propargylamine compound from a propargyl compound by a simple operation without using a special facility, using ammonia as a reaction reagent, without producing a dipropatygylamine compound and a tripropargylamine compound as by-products.
