Procedure

To a solution of 4-(3-dimethylamino-propoxy)-3-(2-methyl-2H-pyrazol-3-yl)-phenylamine (57.3 mg, 0.209 mmol) in CH2Cl2 (2 mL) was added 3-chloro-4-fluorophenyl isocyanate (0.30 μL, 0.241 mmol) and stirred for two hours. The resulting material was purified by solid phase extraction (SCX, 1 gram cartridge), eluting with methanol (30 mL) followed by 2M NH3 in methanol (30 mL). The NH3 containing fractions were dried in vacuo to afford Compound 135 as a colorless solid (66.2 mg, 71%). LCMS m/z (%)=446 (M+H35Cl, 100), 448 (M+H37Cl, 35), 1H NMR (400 MHz, DMSO-d6) δ: 8.87 (bs, 1H), 8.69 (bs, 1H), 7.81-7.77 (m, 1H), 7.47-7.42 (m, 2H), 7.37 (d, J=2.71 Hz, 1H), 7.35-7.26 (m, 2H), 7.09 (d, J=8.98 Hz, 1H), 6.24 (d, J=1.83 Hz, 1H), 3.98 (t, J=6.36 Hz, 2H), 3.65 (s, 3H), 2.19 (t, J=7.04 Hz, 2H), 2.07 (s, 6H), 1.77-1.69 (m, 2H).
