Procedure

To a solution of 4-(3-dimethylamino-propoxy)-3-(2-methyl-2H-pyrazol-3-yl)-phenylamine (38.3 mg, 0.140 mmol) in CH2Cl2 (2 mL) was added 4-methoxyphenyl isocyanate (0.21 μL, 0.162 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 131 as a colorless solid (53.1 mg, 90%). LCMS m/z (%)=424 (MH+) (100), 1H NMR (400 MHz, DMSO-d6) δ: 8.49 (bs, 1H), 8.43 (bs, 1H), 7.44 (d, J=1.86 Hz, 1H), 7.42 (dd, J=8.92, 2.73 Hz, 1H), 7.36 (d, J=2.71 Hz, 1H), 7.33 (d, J=9.09 Hz, 2H), 7.07 (d, J=8.96 Hz, 1H), 6.85 (d, J=9.09 Hz, 2H), 6.23 (d, J=1.82 Hz, 1H), 3.96 (t, J=6.35 Hz, 2H), 3.71 (s, 3H), 3.65 (s, 3H), 2.18 (t, J=7.05 Hz, 2H), 2.07 (s, 6H), 1.77-1.69 (m, 2H).
