Reaction Steps

3-Nitro-5-trifluoromethylaniline (0.8 g; 4 mmol) was suspended in pyridine (5 mL), methanesulfonylchloride (0.6 mL; 8 mmol) was added at 0° C. and the mixture stirred for 5 hours at room temperature. A solution of sodium bicarbonate was then added to the reaction mixture and the precipitate obtained was washed with diluted hydrochloric acid and dried. 0.6 g (2.11; 52.8% yield) of N-(3-nitro-5-trifluoromethyl-phenyl)-methylsulfonamide were obtained as solid.
