3-(4-Bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine (0.036 g, 0.13 mmol) was treated with 2-biphenylyl isocyanate (0.027 g, 24.0 μL, 0.14 mmol, 1.05 equiv.) in CH2Cl2 (1 mL), in a similar manner as described in Example 1.10 to afford Compound 22 (0.031 g, 0.06 mmol, 51%) as a white powder. LCMS m/z (%)=477 (M+H79Br, 100), 479 (M+H81Br, 100). 1H NMR (400 MHz, acetone-d6) δ: 8.41 (s, 1H), 8.17 (d, J=8.3 Hz, 1H), 7.60 (d, J=2.7, 9.0 Hz, 1H), 7.43-7.51 (m, 3H), 7.37-7.43 (m, 3H), 7.29-7.37 (m, 2H), 7.24 (s, 1H), 7.20 (dd, J=1.6, 7.6 Hz, 1H), 7.11 (dd, J=1.0, 7.4 Hz, 1H), 7.08 (d, J=9.0 Hz, 1H), 3.80 (s, 3H), 3.66 (s, 3H).
