Reaction Steps

3-(4-Bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine (0.034 g, 0.12 mmol) was treated with benzyl isocyanate (0.017 g, 16.0 μL, 0.13 mmol, 1.05 equiv.) in CH2Cl2 (1 mL), in a similar manner as described in Example 1.10 to afford Compound 74 (0.031 g, 0.08 mmol, 62%) as a solid film. LCMS m/z (%)=415 (M+H79Br, 86), 417 (M+H81Br, 100). 1H NMR (400 MHz, acetone-d6) δ: 8.05 (s, 1H), 7.64 (dd, J=2.7, 9.0 Hz, 1H), 7.47 (s, 1H), 7.40 (d, J=2.7 Hz, 1H), 7.27-7.37 (m, 4H), 7.22 (t, J=7.0 Hz, 1H), 7.07 (d, J=9.0 Hz, 1H), 6.21 (s, 1H), 4.41 (d, J=4.0 Hz, 2H), 3.79 (s, 3H), 3.66 (s, 3H).
