Reaction Steps

To a solution of 4-(3-dimethylamino-propoxy)-3-(2-methyl-2H-pyrazol-3-yl)-phenylamine (45.6 mg, 0.166 mmol) in CH2Cl2 (2 mL) was added phenyl isocyanate (0.20 μL, 0.184 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 145 as a colorless solid (45.3 mg, 69%). LCMS m/z (%)=394 (M+H, 100), 1H NMR (400 MHz, DMSO-d6) δ: 8.64 (bs, 1H), 8.59 (bs, 1H), 7.48-7.41 (m, 4H), 7.37 (d, J=2.71 Hz, 1H), 7.29-7.23 (m, 2H), 7.09 (d, J=8.97 Hz, 1H), 6.98-6.92 (m, 1H), 6.24 (d, J=1.85 Hz, 1H), 3.97 (t, J=6.36 Hz, 2H), 3.66 (s, 3H), 2.19 (t, J=7.04 Hz, 2H), 2.07 (s, 6H), 1.77-1.68 (m, 2H).
