To a solution of (3-amino-2,6-difluorophenyl)(quinoxalin-6-yl)methanone (40 mg, 0.15 mmol, 1.0 eq.) in DCM (5 mL) were added TEA (42.4 mg, 0.42 mmol, 3.0 eq.) and 1-fluoro-3-isocyanatobenzene (23.3 mg, 0.17 mmol, 1.2 eq.). The resulting mixture was stirred at rt for 1 h, then concentrated. The resulting residue was purified via flash column chromatography (PE/EA=1/1, v/v) to afford 1-(2,4-difluoro-3-(quinoxaline-6-carbonyl)phenyl)-3-(3-fluorophenyl)urea (10.5 mg, 16.7%). LRMS (M−H+) m/z caculated 423.1. found 423.1. 1H NMR (DMSO-d6, 400 MHz) δ 9.31 (s, 1H), 9.11-9.13 (d, 2H), 8.76 (s, 1H), 8.46 (s, 1H), 8.33-8.34 (m, 3H), 7.49-7.52 (d, 1H), 7.32-7.35 (m, 2H), 7.10-7.12 (d, 1H), 6.82 (t, 1H).
