ABSTRACT:
A method of preparing lysergol derivatives, particularly 10.alpha.-methoxy lumilysergol, 1-methyl-10.alpha.-methoxy-lumilysergol and C8 esters of 1-methyl-10.alpha.-methoxy-lumilysergol, is provided characterized in that lysergol esters are subjected to photo-chemical reaction in methanol/sulphuric acid to form esters of 10.alpha.-methoxy lumilysergol. The esters can be subsequently hydrolyzed to obtain 10.alpha.-methoxy-lumilysergol, or can be transesterified with salts of other acids and/or N-methylated.
