Conditions

Temperature
130 °C

Procedure

2,4-Dichloronitrobenzene (10 g, 52 mmol) was added ClSO3H (8 ml, 120 mmol) dropwise under ice-water bath. The mixture was stirred at 130° C. for 26 h. The mixture was cooled to rt and poured onto ice-water. The resulting precipitates were collected by filtration and dried under reduced pressure to give 9 g (60%) of the title compound as brown solids.
