Procedure

To a solution of 4-(3-dimethylamino-propoxy)-3-(2-methyl-2H-pyrazol-3-yl)-phenylamine (24.6 mg, 0.090 mmol) in CH2Cl2 (2 mL) was added 4-fluorophenyl isocyanate (0.12 μL, 0.107 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 125 as a colorless solid (27.0 mg, 73%). LCMS m/z (%)=412 (M+H, 100), 1H NMR (400 MHz, DMSO-d6) δ: 8.67 (bs, 1H), 8.58 (bs, 1H), 7.48-7.41 (m, 4H), 7.36 (d, J=2.70 Hz, 1H), 7.14-7.06 (m, 3H), 6.23 (d, J=1.82 Hz, 1H), 3.97 (t, J=6.34 Hz, 2H), 3.65 (s, 3H), 2.18 (t, J=7.05 Hz, 2H), 2.07 (s, 6H), 1.77-1.68 (m, 2H).
