An object of the invention is to find out intermediates usful for the synthesis of pyrazol-fused ring derivatives (such as 7-phenylpyrazolo[1,5-a]pyridine derivatives) and a method for producing the same. A method for producing compound represented by the general formula (II), wherein Z
1
and Z
2
each independently represents a methine group or a nitrogen atom; R
1
represents an ethyl group or the like; R
5
represents a hydrogen atom or the like; R
2
and R
3
each independently represents a C
1-6
alkyl group or the like, salts thereof, or solvates of both, comprising the step of: reacting a compound represented by the general formula (I), wherein Z
1
, Z
2
, R
5
, R
1
, R
2
and R
3
each has the same definition as described above, with an organometallic reagent; and then reacting the resulting product with pentafluoroiodobenzene.
