A solution of 3-(4-chloro-2-methyl-2H-pyrazol-3-yl)-4-(2-morpholin-4-yl-ethoxy)-phenylamine (0.040 g, 0.12 mmol) in CH2Cl2 (1 mL) was treated with 3-chlorophenyl isocyanate (0.015 mL, 0.125 mmol). The reaction was stirred overnight, and concentrated and purified by RP-HPLC. Lyophilization afforded a TFA salt as a brown solid (0.016 g, 27%). LCMS m/z (%)=490 (M+H35Cl35Cl, 100), 492 (M+H35Cl37Cl, 76), 494 (M+H37Cl37Cl, 15). 1H NMR (400 MHz, DMSO-d6) δ: 8.92 (s, 1H), 8.79 (s, 1H), 7.74 (t, J=2.0 Hz, 1H), 7.70-7.63 (m, 1H), 7.57 (dd, J=2.7, 6.3 Hz, 1H), 7.41 (d, J=2.7 Hz, 1H), 7.36-7.28 (m, 2H), 7.21 (d, J=9.0 Hz, 1H), 7.04 (dt, J=1.9, 7.4 Hz, 1H), 4.22-4.15 (m, 1H), 4.11-4.05 (m, 1H), 3.70 (s, 3H), 3.56-3.51 (m, 4H), 2.66-2.48 (m, 2H), 2.42-2.30 (m, 4H).
