Zusammenfassung:Disclosed is a method for producing a 3-(substituted oxy)-4-pyridazinol derivative represented by the general formula (I), which comprises reacting a compound represented by the general formula (III) with a compound represented by the general formula (IV) in the presence or absence of a base and in the presence or absence of a solvent. According to the present invention, a 3-(substituted oxy)-4-pyridazinol derivative represented by the general formula (I) can be produced in high yield and with high selectivity.
