Procedure

To 20 % ice-cooled fuming sulfuric acid (50 g), 4-(N-acetylamino)-1-chloro-3-fluorobenzene (9.4 g) was dissolved, followed by gradual addition of fuming nitric acid (3.5 g) while keeping the temperature at 0° to 5° C. The resultant mixture was stirred at the same temperature for 1 hour and poured into ice (50 g). The precipitated crystals were collected by filteration, and the filtrate was washed with water and dried to give 11.6 g of 4-(N-acetylamino)-1-chloro-5-fluoro-2-nitrobenzene. M.P., 124.7°-125.7° C.
