Procedure

To a solution of 3-(2-isopropyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine (0.1 g, 0.433 mmol) in CH2Cl2, was added 4-chlorophenyl isocyanate (0.0733 g, 0.476 mmol) and stirred overnight. The resulting precipitate was filtered and washed with methylene chloride/hexane (1:1), and dried in vacuo to yield Compound 43 as a colorless solid (0.050 g, 30%). LCMS m/z (%)=386 M+H+ (37Cl, 26), 385 M+H+ (35Cl, 94), 1H NMR (400 MHz, DMSO-d6) δ: 8.84 (bs, 1H), 8.77 (bs, 1H), 7.48 (d, J=1.91 Hz, 1H), 7.46 (d, J=1.84 Hz, 1H), 7.44 (d, J=3.65 Hz, 1H), 7.33 (t, 1H), 7.3 (s, 1H), 7.29 (d, J=7.68 Hz, 2H), 7.07 (d, J=8.9 Hz, 2H), 6.13 (d, J=1.83 Hz, 1H), 4.25 (m, 1H), 3.7 (s, 3H), 1.3 (d, J=6.76 Hz, 6H).
