Procedure

3-(4-Bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine (0.032 g, 0.11 mmol) was treated with 4-(trifluoromethoxy)phenyl isocyanate (0.025 g, 18.4 μL, 0.12 mmol, 1.05 equiv.) in CH2Cl2 (1 mL), in a similar manner as described in Example 1.2 to afford Compound 19 (0.032 g, 0.07 mmol, 58%) as a white solid. LCMS m/z (%)=485 (M+H79Br, 92), 487 (M+H81Br, 100). 1H NMR (400 MHz, acetone-d6) δ: 8.31 (s, 1H), 8.19 (s, 1H), 7.70 (d, J=9.0 Hz, 1H), 7.66 (d, J=8.4 Hz, 2H), 7.51 (s, 1H), 7.45 (s, 1H), 7.25 (d, J=8.4 Hz, 2H), 7.15 (d, J=8.9 Hz, 1H), 3.83 (s, 3H), 3.70 (s, 3H).
