3-(4-Bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine (0.037 g, 0.13 mmol) was treated with 3-cyanophenyl isocyanate (0.020 g, 0.14 mol, 1.05 equiv.) in CH2Cl2 (1 mL), in a similar manner as described in Example 1.10 to afford Compound 21 (0.032 g, 0.08 mmol, 58%) as a white powder. LCMS m/z (%)=426 (M+H79Br, 99), 428 (M+H81Br, 100). 1H NMR (400 MHz, acetone-d6) δ: 8.45 (s, 1H), 8.26 (d, J=9.6 Hz, 1H), 8.05 (t, J=1.7 Hz, 1H), 7.74 (dd, J=1.5, 8.2 Hz, 1H), 7.70 (dd, J=2.7, 9.0 Hz, 1H), 7.50 (s, 1H), 7.48 (t, J=8.1 Hz, 1H), 7.43 (d, J=2.7 Hz, 1H), 7.36 (d, J=7.6 Hz, 1H), 7.15 (d, J=9.0 Hz, 1H), 3.83 (s, 3H), 3.69 (s, 3H).
