Abstract
A method for making an amine includes the steps of heating a reaction mixture including a nitrile, an acid, water and a substrate compound capable of generating a carbonium ion by reaction with the acid to generate a first reaction intermediate; treating the first reaction intermediate with an acid in the presence of a primary alkanol to form a second reaction intermediate and an alkyl ester; separating the alkyl ester from the second reaction intermediate; and treating the second reaction intermediate with a base to form the amine.
