Reaction Steps

To a DMF (20 mL) solution of 3-chloro-4-fluorobenzaldehyde (500 mg), potassium carbonate (1.20 g) and imidazole (275 mg) were added one by one, and the reaction solution was agitated at 80° C. overnight. Water and ethyl acetate were added to the reaction solution, and the organic layer was partitioned. After the obtained organic layer was washed with a saturated saline solution, it was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The obtained residue was purified by silica gel chromatography (elution solvent: ethyl acetate->ethyl acetate:methanol=10:1), and 548 mg of the title compound was obtained. The physical properties of the compound are as follows.
