Participants

Reaction Steps

3-(4-Bromo-2-methyl-2H-pyrazol-3-yl)-4-(4-chloro-benzyloxy)-phenylamine (0.032 g, 0.08 mmol) was treated with 4-fluorophenyl isocyanate (0.014 g, 11.1 μL, 0.10 mmol, 1.2 equiv.) in CH2Cl2 (1 mL), in a similar manner as described in Example 1.2 to afford Compound 64 (0.023 g, 0.04 mmol, 54%) as a white solid. LCMS m/z (%)=545 (M+H79Br35Cl, 65), 547 (M+H81Br35Cl, 100), 549 (M+H81Br37Cl, 25). 1H NMR (400 MHz, acetone-d6) δ: 8.13 (s, 2H), 7.66 (dd, J=2.7, 9.0 Hz, 1H), 7.51-7.56 (m, 3H), 7.50 (s, 1H), 7.46 (d, J=2.7 Hz, 1H), 7.37 (d, J=8.7 Hz, 2H), 7.33 (d, J=8.7 Hz, 2H), 7.21 (d, J=9.0 Hz, 1H), 7.05-7.75 (m, 2H), 5.14 (AB quartet, J=12.3, 24.8 Hz, 2H), 3.69 (s, 3H).
