To a mixture of 5-chloro-2-nitro-4-trifluoromethyl-phenylamine (1.50 g, 6.26 mmol), potassium carbonate (1.72 g, 12.5 mmol), and DMF (31 mL) was added 1-propanethiol (0.620 mL, 6.86 mmol). The reaction mixture was heated at 90° C. for 16 h, then allowed to cool to 23° C. and poured into ice/brine (300 mL). The resulting yellow precipitate was collected to yield the titled compound (1.67 g, 95%). MS (ESI/CI): mass calcd. for C10H11F3N2O2S, 280.1; m/z found, 281.0 [M+H]+. 1H NMR (400 MHz, CDCl3): 8.41 (s, 1H), 6.58 (s, 1H), 6.36 (br s, 2H), 2.97 (t, J=7.3 Hz, 2H), 1.87-1.72 (m, 2H), 1.10 (t, J=7.4 Hz, 3H).
