Document Type and Number:
Japanese Patent JPH0747587
Kind Code:
B2
Abstract:
A method of preparing lysergol derivatives, particularly 10α-methoxy lumilysergol, 1-methyl-10a-methoxy-lumilysergol and C8 esters of 1-methyl-10a-methoxy-lumilysergol, is provided characterised in that lysergol esters are subjected to photo-chemical reaction in methanol/sulphuric acid to form esters of 10a-methoxy lumilysergol. The esters can be subsequently hydrolyzed to obtain 10α-methoxy-lumilysergol, or can be transesterified with salts of other acids and/or N-methylated.
