Benzene, 1-chloro-3-isocyanato- → 1-(3-Chloro-phenyl)-3-[4-(3-dimethylamino-propoxy)-3-(2-methyl-2H-pyrazol-3-yl)-phenyl]-urea

Participants

Reaction Steps

To a solution of 4-(3-dimethylamino-propoxy)-3-(2-methyl-2H-pyrazol-3-yl)-phenylamine (47.4 mg, 0.173 mmol) in CH2Cl2 (2 mL) was added 3-chlorophenyl isocyanate (0.24 μL, 0.197 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 134 as a colorless solid (31.0 mg, 42%). LCMS m/z (%)=428 (M+H35Cl, 100), 430 (M+H37Cl, 39), 1H NMR (400 MHz, DMSO-d6) δ: 8.64 (bs, 1H), 8.59 (bs, 1H), 7.47-7.41 (m, 3H), 7.45 (d, J=1.79 Hz, 1H), 7.37 (d, J=2.71 Hz, 1H), 7.30-7.23 (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), 1.77-1.69 (m, 2H).
