Abstract
The invention relates to a novel stereoselective process for the preparation of dihdyrolysergol from lysergol by hydrogenation in the presence of solvent and palladium catalyst applied on a carrier, which comprises hydrogenating lysergol in the presence of one or more aprotic solvent(s) containing tertiary nitrogen atom(s) and a palladium catalyst applied on activated carbon, and recovering the product obtained from the reaction mixture in a known manner.
