Process for the preparation of mono-substituted lysergic amides, according to which lysergic acid and a primary amine are condensed together in the presence of carbodiimides. However, when this reaction is used, an appreciable yield can not be obtained, since the optically active lysergic acid is almost completely converted to the racemic form in the course of the reaction.
