51.8 g of 2-(N-ethylanilino)ethanol and 31.7 g of triethylamine were dissolved in 320 ml of acetone, and to this solution 24.9 g of acetyl chloride was slowly added dropwise while stirring under ice cooling. This mixture was stirred for 3 hours at room temperature, and the reaction solution was poured into 500 ml of water. An organic layer was extracted with ethyl acetate, washed with water, and then dried over sodium sulfate. The solvent was distilled off under reduced pressure to obtain 64.9 g of 2-(ethylphenylamino)ethyl acetate.
