A mixture of N-methylcarbonyl 2,3-dichloro-6-nitroaniline (0.90 g, 3.6 mmol), 2,4-dichloro-phenol (0.59 g, 3.6 mmol) and potassium carbonate (1.0 g, 7.2 mmol), in 20 ml of DMSO, is stirred at 90° for 3 hours. The reaction is then cooled and poured onto about 60 g of ice. A yellow solid is collected by filtration to give N-methylcarbonyl 2-chloro-3-(2,4-dichloro-phenoxy)-6-nitroaniline.
