Abstract
6-methyl-ergol-9-ene of general formula (I) is prepd from elymoclavine derivs. of formula (II). (II) is isomerised in an non-polar solvent, at the solvents bpt in the presence of an aluminium-oxide-hydrate catalyst, which also acts as an adsorbent. The product is dissolved off the catalyst and isolated in its unchanged as salt form. In formula (I) R1=H, short C. chain alkyl or hydroxy-methyl gp.; R2=halo, acyl-oxy-gp., or a hydroxy gp., provided R1 is not a Hydrogen atom and X=H or halo.
