Procedure

To a solution of 3-(4-chloro-2-isopropyl-2H-pyrazol-3-yl)-4-methoxy-phenylamine (0.1 g, 0.433 mmol) in CH2Cl2, was added 3,4-difluoro-phenyl isocyanate (0.075 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 55 as a colorless solid (0.062 g, 35%). LCMS m/z (%)=423 M+H+ (37Cl, 23), 421 M+H+ (35Cl, 67), 1H NMR (400 MHz, acetone-d6) δ: 8.199 (d, J=2.44 Hz, 1H), 8.181 (d, J=2.42 Hz, 1H), 8.166 (d, J=2.37 Hz, 1H), 8.147 (d, J=2.08 Hz, 1H), 8.106 (d, J=2.65 Hz, 1H), 8.085 (d, J=2.68 Hz, 1H), 7.967 (s, 1H), 7.880 (d, J=2.61 Hz, 1H), 7.627 (t, 1H), 7.594 (d, J=3.86 Hz, 1H) 7.563 (d, J=8.96 Hz, 1H), 4.669 (m, 1H), 4.242 (s, 3H), 1.874 (d, J=6.61 Hz, 3H), 1.713 (d, J=6.61 Hz, 3H).
