Furfurylamine (15.0 g) and 17.2 g of triethylamine were dissolved in 75 mL of toluene, 20.8 g of ethyl chloroacetate was added thereto and the mixture was heated to reflux for 3 hours. After the reaction solution was cooled, 100 mL of water was added thereto and the mixture was subjected to extraction with ethyl acetate. The organic layer was washed with water and a saturated solution of sodium chloride and dried over anhydrous magnesium sulfate and the solvent was evaporated therefrom in vacuo. The residue was purified by silica gel column chromatography to give 18.2 g of an objective compound as yellow liquid.
