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.
The present invention provides a selective A2A receptor antagonist. In particular, the present invention provides a selective A2A receptor antagonist represented by general formula (I), a pharmaceutical composition comprising same, and pharmaceutical use and therapeutic use thereof. The definition of each group in the general formula (I) is as described in the description.

Antagonism of the adenosine A(2a) receptor offers great promise in the treatment of Parkinson's disease. In the course of exploring pyrazolo[4,3-e]-1,2,4-triazolo[1,5-c]pyrimidine A(2A) antagonists, which led to clinical candidate SCH 420814, we prepared 1,2,4-triazolo[1,5-c]pyrimidines with potent and selective (vs A(1)) A(2a) antagonist activity, including oral activity in the rat haloperidol-induced catalepsy model. Structure-activity relationships and plasma levels are described for this series. (C) 2008 Elsevier Ltd. All rights reserved.
