Abstract
A process for obtaining D-2-substituted and 8-substituted 6-alkyl ergolines, characterized by demethylating a compound of formula I **(See formula)** where X is C1, Br, I, CH3 or CN and R is CH2-CN or (see formula), to give a compound of formula II **(See formula)** where X and R are as defined above and re-alkylating the compound of formula II to give a compound of formula III **(See formula)** where X and R are as defined above and R'is C1-C4 primary alkyl.
