A novel process is disclosed for the preparation of derivatives of lysergol having the general formula: ##STR1## According to this process lysergol is directly used as the starting compound and, after the methylation at the 1 position of the corresponding 10 alpha-methoxy-lumilysergol, the methylated compound is directly esterified with a carboxylic acid R--COOH, the acid being selected in the group comprising aliphatic, cycloaliphatic, aromatic, and heterocyclic carboxylic acids, containing up to 10 carbon atoms. |
