摘要 |
<p>The present invention describes processes for the synthesis of 2-(furan-2-yl)-7-[2-[4-[4-(2-methoxyethoxy)phenyl]piperazin-l-yl] ethyl]-7H-pyrazolo[ 4,3-e ][1,2,4]- triazolo[1,5c] pyrimidin-5-amine (Preladenant) represented by the structure of formula (1 ), and solvates and salts thereof, especially salts with pharmaceutically acceptable acids. The process of the present invention is useful not only for Preladenant production, but also for the preparation of other biologically active compounds of general formula (17), such as A2a receptor antagonists used for the treatment of central nervous system diseases, among others. The present invention further relates to certain intermediates formed in such processes.</p> |
