Versuchsvorschrift

3-(4-Bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine (0.035 g, 0.12 mmol) was treated with 4-chloro-3-(trifluoromethyl)phenyl isocyanate (0.027 g, 0.12 mmol, 1.0 equiv.) in CH2Cl2 (2 mL), in a similar manner as described in Example 1.2 to afford Compound 6 (0.051 g, 0.10 mmol, 81%) as a white solid. LCMS m/z (%)=503 (M+H79Br35Cl, 78), 505 (M+H81Br35Cl, 100), 507 (M+H81Br37Cl, 28). 1H NMR (400 MHz, acetone-d6) δ: 8.52 (s, 1H), 8.27 (s, 1H), 8.13 (s, 1H), 7.74 (b, J=8.7 Hz, 1H), 7.68 (d, J=9.0 Hz, 1H), 7.53 (d, J=8.7 Hz, 1H), 7.49 (s, 1H), 7.43 (s, 1H), 7.14 (d, J=9.0 Hz, 1H), 3.82 (s, 3H), 3.68 (s, 3H).
