To a mixture of sodium isopropylsulfinate (3.3 g) and N-methyl-2-pyrrolidinone (20 mL), 2,3-dichloronitrobenzene (4 g) was added and stirred overnight at 70° C. The reaction mixture was diluted with water, and the precipitated solid was collected by filtration and washed with diethyl ether to give 3-chloro-2-isopropylsulfonyl-1-nitrobenzene (3.0 g) as a white solid.
