    摘要: Processes for the preparation of esters of N.sub.1 -methyl-10.alpha.-methoxylumilysergol are described, in which lysergol esters are subjected to N-methylation and subsequently to photochemical reaction with methanol/H.sub.2 SO.sub.4. The esters of N.sub.1 -methyl-10-methoxylumilysergol obtained in this way can then be saponified or converted directly into other esters.

    摘要: 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.
