Reaction Steps
To a mixture of 25.5 g (150 mmol) of sodium 2-cyclopropyl-6-methylphenoxide and 12.5 g of 2-octanol was added 2.5 g (purity: 99%; 15.0 mmol) of 4-hydroxy-3,6-dichloropyridazine at room temperature. Then, the resultant mixture was heated from room temperature to 140° C. to effect a reaction for 4 hours. After completion of the reaction, the reaction mixture was cooled to room temperature, and 100 g of pure water and 100 g of toluene were added to the cooled mixture, and stirred for 30 minutes, and an organic phase containing 2-cyclopropyl-6-methylphenol added in an excess amount was separated. Then, the resultant aqueous phase containing a sodium salt of 6-chloro-3-(2-cyclopropyl-6-methylphenoxy)-4-pyridazinol was quantitatively determined by an HPLC internal standard analysis method, which showed that 3.11 g of 6-chloro-3-(2-cyclopropyl-6-methylphenoxy)-4-pyridazinol (yield: 75.2%) and 10.0 mg of 3-chloro-6-(2-cyclopropyl-6-methylphenoxy)-4-pyridazinol (yield: 0.2%) were obtained.
