実験手順

Urea synthesis (General Procedure): To a stirred solution of 3-(4-bromo-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine (0.034 g, 0.12 mol, Example 1.1) in CH2Cl2 (1 mL) was added 4-chloro-2-(trifluoromethyl)phenyl isocyanate (0.029 g, 20.0 μL, 0.13 mmol, 1.05 equiv.) at room temperature. White solid precipitated and was filtered and washed with cold CH2Cl2 to afford Compound 9 (0.037 g, 0.074 mmol, 60%) as a white solid. LCMS m/z (%)=503 (M+H79Br, 77), 439 (M+H81Br, 100). 1H NMR (400 MHz, acetone-d6) δ: 8.82 (s, 1H), 8.22 (d, J=9.6 Hz, 1H), 7.62-7.72 (m, 4H), 7.49 (s, 1H), 7.43 (d, J=2.6 Hz, 1H), 7.15 (d, J=9.0 Hz, 1H), 3.83 (s, 3H), 3.68 (s, 3H).
