Zusammenfassung:	PROBLEM TO BE SOLVED: To industrially and economically advantageously N-alkylate an amine by carrying out the reaction in the presence of a specific catalyst. SOLUTION: When (A) an alcohol (preferably an α,ω-diol) is reacted with (B) an alkylamine or a dialkylamine (preferably monomethylamine, etc.), the reaction is carried out in the presence of (C) a catalyst prepared by including 0-2 wt.% BaO, Cr2 O3 and/or ZnO in copper and magnesium silicate as a base regardless thereof for each time as the catalyst. The component C preferably contains 30-60 wt.% CuO and has preferably at least 100 m /g BET specific surface area. The reaction is preferably conducted in the liquid phase under 50-300 bars pressure.
