2 ml of pyridine is added to 30 ml of a solution of 3-methoxyaniline (4.92 g, 40 mmol) in dichloromethane and the mixture is stirred for 5 minutes, while maintaining the temperature inside vessel at lower than 0° C., and thereto 20 ml of a solution of chloroacetyl chloride (6.78 g, 60 mmol) in dichloromethane is drop-added slowly. A reaction is carried out at room temperature for 12 hours after completion of drop-addition, and then terminated. The reaction solution is washed with 5% of HCl (30 ml×3), 5% of NaOH (30 ml×3), water (30 ml×3), and saturated saline (30 ml) successively, dried over anhydrous magnesium sulfate and filtered. The filtrate is evaporated to remove the solvent to obtain 6.43 g of 2-chloro-N-(3-methoxyphenyl)acetamide, with a yield of 80.7%.
