Procedure

3-(4-Bromo-2-methyl-2H-pyrazol-3-yl)-4-phenethyloxy-phenylamine (0.029 g, 0.08 mmol) was treated with 4-fluorophenyl isocyanate (0.013 g, 11.0 μL, 0.09 mmol, 1.2 equiv.) in CH2Cl2 (1 mL), in a similar manner as described in Example 1.10 to afford Compound 65 (0.030 g, 0.06 mmol, 74%) as a solid film. LCMS m/z (%)=509 (M+H79Br, 100), 511 (M+H81Br, 97). 1H NMR (400 MHz, acetone-d6) δ: 8.22 (s, 2H), 7.63 (d, J=8.9 Hz, 1H), 7.48-7.56 (m, 3H), 7.41 (s, 1H) 7.15-7.28 (m, 3H), 7.08-7.16 (m, 3H), 7.03 (t, J=8.7 Hz, 2H), 4.08-4.30 (m, 2H), 3.50 (s, 3H), 2.86-3.06 (m, 2H).
