Abstract: The manufacture of N-disubstituted 1-aminoalk-2-yn-4-ols by reacting a secondary amine, e.g. a dialkylamine, formaldehyde and an acetylene-alcohol by a Mannich reaction, using a copper catalyst, takes place with better yield and at a higher rate if carried out in the presence of iodine or of a bromide or iodide.
