Abstract
"Process for the preparation of carboxylic acid amides" which correspond to the general formula ** (See formula) ** wherein the nucleus A can carry one or more substituents, in particular substituents belonging to the class of the halogen atoms, lower alkoxy groups and lower alkoxy groups, Y designates 0 or SO2, Z1 designates H or a lower alkoxy group, n denotes a significant integer from 1 to 4 and Am designates NH2 or the radical of a primary or secondary amine, this being a cyclamine, characterized in that an ester is reacted which corresponds to the formula ** (See formula) ** wherein Z2 designates an alcoralkyl or aralkohyl radical and a diamine corresponding to the formula ** (See formula) ** in substantially equimolar quantities in the presence of an organic diluent which is chemically inert in relation to the ester, the diamine and the final product and which forms an azeotrope with the alcohol Z2OH, the reaction being carried out at a temperature at least equal to the boiling point of the azeotrope.
