A solution of 1-chloromethyl-3-nitro-5-trifluoromethyl-benzene (520 mg; 2.170 mmol) and methanesulfinic acid sodium salt (664 mg; 6.511 mmol) in Methanol (10 ml) of was refluxed overnight. The reaction was then cooled to room temperature and the product precipitated was filtered and diluted with dichloromethane. The solid was removed and the organic phase was concentrated in vacuo 520 mg (2 mmol; 85% yield) of 1-methylsulfonylmethyl-3-nitro-5-trifluoromethyl-benzene were obtained.
