| titleOfInvention | Process for the preparation of intermediates used in the synthesis of progesterone antagonists (synthesis of onapristone) |
| abstract | A process for the preparation of intermediates of the general formula III <IMAGE> in which Z, R<1> and R<2> have the meaning indicated in the description, is described and entails a compound of the general formula II <IMAGE> in which R<2> and Z have the meaning indicated in formula III, being reacted with a compound of the formula <IMAGE> (Hal = halogen) with the addition of a Cu(I) salt. These intermediates are suitable for the preparation of antigestagens (especially Onapristone, EP-A 0 129 499). |
