الإجراء التجريبي

4-Nitro-2-trifluoromethyl-phenylamine (5.6 g) and N-chlorosuccinimide (4.0 g) were suspended in acetonitrile (15 mL) and heated to 150° C. for 10 minutes in a sealed microwave process vial. Ethyl acetate (80 mL) was added and the organic phase was washed with 5% aqueous NaOH (2×50 mL), water (2×50 mL) and brine (2×50 mL). The organic phase was dried over magnesium sulfate and concentrated in vacuo. The crude product was purified by flash chromatography to furnish 4.9 g (75% yield) of the title compound as a yellow solid. 1H NMR (500 MHz, CDCl3): 5.35 (b, 2H), 8.35 (b, 1H), 8.37 (b, 1H).
