The invention aim at finding intermediates useful in the synthesis of pyrazole- fused ring derivatives (such as 7-phenylpyrazolo[1,5-a]pyridine derivatives) and a process for the production thereof. A process for the production of compounds represented by the general formula (II), salts thereof, or solvates of both, characterized by reacting a compound represented by the general formula (I) with an organometallic reagent and then reacting the resulting product with pentafluoroiodobenzene: wherein Z<sup>1</sup> and Z<sup>2</sup> are each independently a methine group or a nitrogen atom; R<sup>1</sup> is ethyl or the like; R<sup>5</sup> is hydrogen or the like; and R<sup>2</sup> and R<sup>3</sup> are each independently C<sub>1-6</sub> alkyl or the like.

L'invention vise à trouver des intermédiaires utiles dans la synthèse de dérivés pyrazolés à cycles fusionnés (tels que les dérivés du 7-phénylpyrazolo[1,5-a]pyridine) et un processus de production de ceux-ci. Un processus de production de composés représentés par la formule générale (II), sels ou solvates des deux, caractérisés par leur réaction à un composé représenté par la formule générale (I) avec un réactif organométallique et faisant ensuite réagir le produit obtenu avec du pentafluoroiodobenzène : (I) (II) où Z<sup>1</sup> et Z<sup>2</sup> sont chacun indépendamment un groupe méthine ou un atome d'azote ; R<sup>1</sup> est de l~éthyle ou similaire ; R<sup>5</sup> est de l'hydrogène ou similaire ; et R<sup>2</sup> et R<sup>3</sup> sont chacun indépendamment un alkyle en C<sub>1-6</sub> ou similaires.
