Reaction Conditions

Reaction Steps

To a mixture of 4,5-dichloro-2-nitro-phenylamine (3.00 g, 14.5 mmol) and DMF (72 mL) was added K2CO3 (5.31 g, 29.0 mmol) and phenyl-methanethiol (3.94 g, 31.7 mmol). The mixture was heated to 70° C. for 18 h and then cooled to 23° C. The reaction mixture was dissolved in EtOAc (200 mL), washed with saturated sodium bicarbonate solution (100 mL), washed with brine (3×100 mL). The organic layers were combined, dried, filtered, and concentrated under reduced pressure. The residue was purified (FCC) (5-45% EtOAc/hexanes) to yield the titled compound (2.39 g, 56%). MS (ESI/CI): mass calcd. for C13H11ClN2O2S, 294.0; m/z found, 295.0 [M+H]+. 1H NMR (600 MHz, DMSO-d6): 7.96 (s, 1H), 7.56 (s, 2H), 7.50 (d, J=7.2 Hz, 2H), 7.37 (t, J=7.5 Hz, 2H), 7.31 (t, J=7.4 Hz, 1H), 7.05 (s, 1H), 4.27 (s, 2H).
