General procedure for the synthesis of 1-chloro-4-methyl-2-nitrobenzene from 4-methyl-2-nitrobenzoic acid: 6.2 mg of silver sulfate, 36.3 mg of copper acetate, 12.5 mg of 2,9-dimethyl-1,10-o-phenanthroline, 36.2 mg of 4-methyl-2-nitrobenzoic acid, and 17.5 mg of sodium chloride were added sequentially to a Silak reactor tube fitted with a magnetic stirrer. NaCl, followed by the addition of 4 mL of dimethyl sulfoxide as solvent. The reaction mixture was heated and stirred at 160 °C for 24 hours under an oxygen atmosphere. Upon completion of the reaction, the reaction was quenched by the addition of appropriate amount of distilled water and extracted three times with ethyl acetate (10 mL each time). The organic phases were combined and concentrated under reduced pressure to give 17.5 mg of 1-chloro-4-methyl-2-nitrobenzene in 51% yield.
