| titleOfInvention | Process for preparing 14,15-dihydro-d-nor-eburnamenine derivatives |
| abstract | FIELD OF THE INVENTION The present invention relates to a novel 14,15 dihydro-D-norburbamenine derivative of the formula Ia and / or Ic, wherein R2 is (C1-C4 alkoxy) carbonyl or a cyano group such that i) a - optionally an acid addition salt of formula IIb, wherein X "is an anion-free anion-liberated l-ethylindolo (3,2-g) indolizine derivative, an acrylic acid derivative of formula III wherein Y is halogen, R2 is the reaction product is hydrogenated by chemical reduction and, if desired, the resulting mixture is separated; for the preparation of a (C 1 -C 4) alkoxy) carbomyl group, optionally 11b from an acid addition salt of the general formula wherein X 'is the in situ release of the 1-ethylindolo [3,2-g] indolizine derivative with an acrylic acid derivative of formula IIP wherein R 1 is (C 1 -C 4 alkoxy) carbonyl; And Y is as defined below, by reacting the resulting 14,15-dihydro-H '-1- |
