Reaction Steps

To 10 ml of ethanol, 0.90 g (2.0 mmol) of 3-[2-chloro-4-(1-ethoxycarbonylethoxy)-5-nitrophenyl]-1-methyl-6-trifluoromethyl-2(1H)-pyridone and 1 g (8.5 mmol) of tin were added, and 2 ml of concentrated hydrochloric acid was added thereto with stirring at room temperature, followed by stirring for 1 hour. After completion of the reaction, excess ethanol was distilled off under reduced pressure, and the residue was neutralized with a saturated sodium hydrogencarbonate aqueous solution and then extracted with ethyl acetate. The organic layer was washed with water and dried over anhydrous magnesium sulfate. The organic layer was distilled off under reduced pressure to obtain 0.7 g (yield: 91%) of the desired product.
