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.
本发明描述了合成2-(呋喃-2-基)-7-[2-[4-[4-(2-甲氧基乙氧基)苯基]哌嗪-1-基]乙基]-7H-吡唑并[4,3-e][1,2,4]-三唑[1,5c]嘧啶-5-胺(Preladenant)的方法,其结构式表示为(1),以及其溶剂化物和盐,尤其是与药用可接受酸的盐。本发明的方法不仅对Preladenant的生产有用,而且对于制备一般式(17)的其他生物活性化合物也有用,例如用于治疗中枢神经系统疾病的A2a受体拮抗剂等。本发明还涉及在这些过程中形成的某些中间体。
