Abstract
Process for obtaining dihydrolysergic acid derivatives and their acid addition salts, characterized in that they are of the general formula I ** (See formula) ** - wherein R1 represents an alkyl group containing from 1 to 4 carbon atoms inclusive, or an aralkyl group containing from 7 to 13 carbon atoms inclusive, with R2 representing a hydrogen atom or an alkyl group containing from 1 to 4 carbon atoms inclusive and R3 an alkyl or hydroxy alkyl group containing from 1 to 4 carbon atoms inclusive, or a cycloalkyl group containing at most 7 carbon atoms inclusive, or R2 together with R3 represent a radical linear chain alkylene containing at most 5 carbon atoms - and, furthermore, by reducing a compound of the general formula II. ** (See formula) ** - wherein R1, R2 and R3 have the above meanings in solution, either with catalytically activated hydrogen or with a solution of an alkali metal in liquid ammonia, and when it is desired to obtain an acid addition salt, it is salified with an inorganic acid or organic (Machine-translation by Google Translate, not legally binding)
