実験手順: p-Chloroaniline (3.82 g) was dissolved in ethyl acetate (30 ml), and chloroacetyl chloride (2.39 ml) was added at room temperature to stir the mixture for 1 hour. After the reaction mixture was heated and stirred at 60° C. for 3.5 hours, crystals deposited were collected by filtration to obtain the title compound (4.78 g). The filtrate was concentrated to about 1/4, and crystals deposited were collected by filtration to obtain the title compound (1.01 g). After the reaction mixture was heated stirred at 60° C. for 3.5 hours crystals deposited were collected by filtration

実験手順: p-Chloroaniline (3.82 g) was dissolved in ethyl acetate (30 mL), and, at room temperature, chloroacetyl chloride (2.39 mL) was added to the solution, followed by stirring for 1 hour. After the reaction mixture was heated and stirred at 60° C. for 3.5 hours, crystals precipitated were collected by filtration, to thereby give the title compound (4.78 g). The filtrate was concentrated to about ¼, and crystals precipitated were collected by filtration, to thereby give the title compound (1.01 g). After the reaction mixture was heated stirred at 60° C. for 3.5 hours crystals precipitated were collected by filtration

実験手順: 3.4 g (30 mol) of 2-chloroacetyl chloride were dissolved in anhydrous dioxane and a solution containing 3.8 g (30 mol) of 4-chloroaniline was added dropwise. After an hour, the batch was poured into ice water, acidified using dilute hydrochloric acid, the supernatant was removed by suction and the residue was washed with water until neutral. The reaction product was recrystallized from ethanol. The yield was 3.2 g. was added dropwise After an hour the supernatant was removed by suction the residue was washed with water until neutral The reaction product was recrystallized from ethanol
