2-Aminobenzaldehyde (650 mg) was dissolved in dichloromethane (20 ml) to prepare a solution. Chloroacetyl chloride (728 mg) was added to the solution, and the mixture was stirred at room temperature overnight. Water was added thereto, and the mixture was extracted with dichloromethane. The dichloromethane layer was washed with water and saturated brine and was dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure, and the residue was purified by column chromatography using chloroform to give 2-chloro-N-(2-formylphenyl)-acetamide (1.05 g, yield 99%).
