Abstract
The invention relates to a process for preparing a .beta.-hydroxyalkylamide, in which alkyl esters are reacted with .beta.-aminoalcohols in the absence of solvents and in the presence of basic catalysts, where, to improve the selectivity, the ratio of equivalents of ester to equivalents of amine is 1:1.001 to 8.
