To a suspension in which 42.8 g of 5-nitroisoindoline had been added to an aqueous potassium carbonate solution (108 g of potassium carbonate, 200 ml of water) was added dropwise 200 ml of an ethyl acetate solution containing 31.2 ml of chloroacetyl chloride at 0° C. over 1 hour. The mixture was further stirred at 0° C. for 45 minutes and precipitates were collected by filtration. The obtained solid-was treated with activated carbon in ethyl acetate and recrystallized to obtain 2-chloroacetyl-5-nitroisoindoline.
