Procedure

3-(4-Bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine (0.035 g, 0.12 mmol) was treated with 4-isopropylphenyl isocyanate (0.022 g, 21.0 μL, 0.13 mmol, 1.05 equiv.) in CH2Cl2 (1 mL), in a similar manner as described in Example 1.10 to afford Compound 23 (0.028 g, 0.06 mmol, 50%) as a solid film. LCMS m/z (%)=443 (M+H79Br, 100), 445 (M+H81Br, 99). 1H NMR (400 MHz, acetone-d6) δ: 8.08 (s, 1H), 8.00 (s, 1H), 7.68 (dd, J=2.6, 8.9 Hz, 1H), 7.49 (s, 1H), 7.40-7.46 (m, 3H), 7.09-7.17 (m, 3H), 3.81 (s, 3H), 3.68 (s, 3H), 2.78-2.92 (m, 1H), 1.21 (s, 3H), 1.20 (s, 3H).
