N-Acetyl-N-(3-aminophenethyl)amine (1.7 g, Production Example 29b) was dissolved in pyridine (5 ml). Under ice-cooling, ethyl chloroformate (1.4 ml) was added dropwise thereinto, followed by stirring at room temperature for one hour. Then, the mixture was ice-cooled again and water was added thereto. The mixture was extracted with ethyl acetate, and the extract was washed with brine and dried over anhydrous magnesium sulfate.
