Procedure

3-(4-Bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine (0.037 g, 0.13 mmol) was treated with 3,5-bis(trifluoromethyl)phenyl isocyanate (0.036 g, 24.0 μL, 0.14 mmol, 1.05 equiv.) in CH2Cl2 (1 mL), in a similar manner as described in Example 1.2 to afford Compound 13 (0.030 g, 0.06 mmol, 43%) as a white solid. LCMS m/z (%)=537 (M+H79Br, 99), 539 (M+H81Br, 100). 1H NMR (400 MHz, acetone-d6) δ: 8.77 (s, 1H), 8.42 (s, 1H), 8.22 (s, 2H), 7.73 (dd, J=2.5, 9.0 Hz, 1H), 7.51 (s, 1H), 7.46 (d, J=2.5 Hz, 1H), 7.18 (d, J=9.0 Hz, 1H), 3.85 (s, 3H), 3.71 (s, 3H).
