Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for producing a pyrazole compound, by which the pyrazole compound useful as an intermediate for synthesizing medicines such as a diabetic medicine can simply be produced in a high yield. SOLUTION: This method for producing the compound of formula (I) [(n) is an integer of 1 to 4; R1is a hydrocarbon group which may have a substitutent] or its salt is characterized by reacting a compound represented by formula (II) (Q is hydroxy group which may have a substituent or an amino group which may have a substituent; R is a hydrocarbon group which may have a substitutent) or its salt with hydrazine or its salt.
