Reaction Steps

To 25 ml of chloroform, 0.6 g (1.5 mmol) of 3-(4-chloro-5-chlorosulfonyl-2-fluorophenyl)-1-methyl-6-trifluoromethyl-2(1H)-pyridone and 1.8 g (26.7 mmol) of methylamine hydrochloride were added, and 6.0 g (59.4 mmol) of triethylamine was dropwise added thereto under cooling with ice, followed by stirring at room temperature for 2 hours. This reaction solution was poured into water and extracted with chloroform. After washing with water and a 10% citric acid aqueous solution, the organic layer was dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure. Then, the obtained residue was purified by silica gel column chromatography to obtain 0.4 g (yield:67) of the desired product. Melting point: 150-151° C.
