Procedure

3-(4-Bromo-2-methyl-5-trifluoromethyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine (0.03 g, 0.08 mmol) was treated with 4-fluorophenyl isocyanate (0.01 g, 8.99 μL, 0.08 mmol, 1.1 equiv.) in CH2Cl2 (2.0 mL), in a similar manner as described in Example 1.102, to afford Compound 39 (0.03 g, 0.05 mmol, 64% yield) as a white solid: LCMS m/z (%)=487 (M+H79Br, 100), 489 (M+H81Br, 93). 1H NMR (400 MHz, MeOH-d4) δ: 7.58 (dd, J=10.0, 2.0 Hz, 1H), 7.42 (dd, J=4.0 Hz, 2H), 7.38 (dd, J=10.0, 2.0 Hz, 1H), 7.16 (d, J=12.0 Hz, 1H), 7.03 (dd, J=12.0, 8.0 Hz, 2H), 3.84 (s, 3H), 3.75 (s, 3H).
