Procedure
To a solution of 3-(4-bromo-2-isopropyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine (0.08 g, 0.258 mmol) in CH2Cl2, was added 3-chloro-4-trifluoromethyl-phenyl isocyanate (0.059 g, 0.263 mmol) and stirred overnight at ambient temperature. The resulting precipitate was filtered and washed with methylene chloride/hexane (1:1), and dried in vacuo to yield Compound 53 as a colorless solid (0.1 g, 73%). LCMS m/z (%)=535 M+H+ (81Br 37 Cl, 39), 533 M+H+ (81Br 35Cl, 100), 531 M+H+ (79Br 35Cl, 63), 1H NMR (400 MHz, DMSO-d6) δ: 8.582 (bs, 1H), 8.456 (bs, 1H), 7.864 (s, 1H), 7.654 (d, J=8.28 Hz, 1H), 7.557 (d, J=2.76 Hz, 1H), 7.536 (d, J=2.76 Hz, 1H), 7.369 (d, J=9.13 Hz, 1H), 4.133 (m, 1H), 3.752 (s, 3H), 1.375 (d, J=6.61 Hz, 3H), 1.217 (d, J=6.61 Hz, 3H).
