実験手順

3-(4-Chloro-2-methyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine was treated with 4-chloro-2-trifluoromethylphenyl isocyanate in a similar manner as described in Example 1.53, providing 4.4 mg (8%) of Compound 79 (Note: Compound 79 did not precipitate out. Therefore, the CH2Cl2 was removed under reduced pressure, the residue was dissolved in 5 mL DMSO, and purified by preparative HPLC): LCMS m/z (%)=461 (M+H37Cl, 60), 459 (M+H35Cl, 100). 1H NMR (400 MHz, acetone-d6) δ: 8.99 (s, 1H), 8.30 (s, 1H), 8.16 (dd, J1=8 Hz, J2=2 Hz, 1H), 8.01 (d, J=8 Hz, 1H), 7.66 (s, 1H), 7.64 (d, J=4 Hz, 1H), 7.45 (d, J=4 Hz, 1H), 7.43 (s, 1H), 7.12 (d, J=8 Hz, 1H), 3.79 (s, 3H), 3.63 (s, 3H).
