Paragraph 0048; 0059, (2016/10/08)
PROBLEM TO BE SOLVED: To provide a method of producing a secondary or tertiary higher amine. SOLUTION: The method of producing a higher amine comprises allowing a primary or secondary amine to react with an alcohol in the presence of at least one species of hydrogen halide selected from hydrogen chloride, hydrogen bromide and hydrogen iodide, or in the presence of a compound capable of producing a hydrogen halide (such as 1,3,5-triazo-2,4,6-triphosphorine-2,2,4,4,6,6-chloride). If the raw material amine is a primary amine, a secondary higher amine and a tertiary higher amine can be produced. If the raw material amine is a secondary amine, a tertiary higher amine can be produced. COPYRIGHT: (C)2012,JPO&INPIT

Learning to cooperate: A straightforward method for the selective N-mono- and dialkylation of amines with alcohols by means of non-metal-based catalysis promoted by TAPC is reported (see scheme). Selectivity of the N-mono- and dialkylation, substrate scope and functional-group tolerance are highlighted with respect to each amine (1° and 2°; aromatic and aliphatic) and alcohol (1°, 2° and 3°; benzylic and aliphatic) component.
