Reaction Steps
4-Nitro-2-trifluoromethylaniline (15 g) and N-chlorosuccinimide (10.7 g) dissolved in acetonitril (100 ml) was heated to 150° C. for 15 minutes in a sealed microwave process vial. The reaction mixture was cooled to ambient temperature and poured into 5% sodium hydroxide (500 ml) and ethylacetate (400 ml). After seperation the organic phase was dried (MgSO4), filtered and concentrated in vacuo, followed by purification by flash chromatography to furnish 17.0 g (97% yield) of the title compound as a yellow solid. LC-MS (m/z) 240 (MH+); tR=4.76, (UV, ELSD) 97%, 96%. 1H NMR (500 MHz, DMSO-d6): 7.15 (s, 2H), 8.15 (d, 1H), 8.40 (d, 1H).
