Reaction Steps

In a falsk, 4.0 g of 2,3-dichloro-5-trifluoromethyl pyridine, 10 ml of dimethyl sulfoxide, 5.1 g of anhydrous potassium carbonate and 2.9 g of p-chlorophenol were charged. The flask was heated in an oil bath at 110° C. to react them with stirring for 2 hours. The completion of the reaction was confirmed by a gas chromatography. The reaction mixture was cooled and poured into suitable amount of water. The reaction product was extracted with methylene chloride and the extracted phase was washed with a diluted sodium hydroxide aqueous solution and then, with water and dried over anhydrous sodium sulfate. Methylene chloride was distilled off under a reduced pressure and the oily residue was distilled to obtain 4.4 g of the object compound having a boiling point of 124°-127° C./2.5 mmHg.
