Versuchsvorschrift

To a solution of 2-nitro-4-(trifluoromethyl)benzene-1-sulfonyl chloride (1.0 g, 1.73 mmol) in CH2Cl2 (50 mL) was added 1-methylpiperazine (0.40 mL, 3.6 mmol). The resulting mixture was allowed to stir at room temperature overnight, then diluted with CH2Cl2 (30 mL), the organic layer was washed with 9% aq. Na2CO3 (10 mL) and brine (10 mL). The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated to afford the title compound as a white solid.
