3.70 g of diethyl (3-chloro-2-pyridyl)malonate and 15 ml of dimethyl sulfoxide were mixed. To the mixture was added 0.95 g of sodium chloride and 0.49 g of water. The mixture was stirred for about 20 minutes at an inner temperature of 135 to 150° C. The reaction mixture was allowed to cool to room temperature, then, water was added to the reaction mixture, and extracted with ethyl acetate. After liquid separation, the organic layer was washed with saturated brine twice, and dried over anhydrous magnesium sulfate, then, concentrated under reduced pressure to obtain 2.57 g of ethyl (3-chloro-2-pyridyl)acetate.
