Participants

Reaction Steps

To a solution of 1-(4-chloro-phenyl)-3-[3-(2-methyl-2H-pyrazol-3-yl)-4-(2-pyrrolidin-1-yl-ethoxy)-phenyl]-urea in cold methanol was added a solution of N-chloro succinimide (0.044 g, 0.3215 mmol) in methanol. The reaction mixture was stirred for 60 minutes. Then the methanol was evaporated and the residue was purified using silica flash chromatography with 15% methanol in DCM as eluant. The fractions containing the product were evaporated and dried in vacuo to afford 1-[3-(4-chloro-2-methyl-2H-pyrazol-3-yl)-4-(2-pyrrolidin-1-yl-ethoxy)-phenyl]-3-(4-chloro-phenyl)-urea (Compound 17) (0.05 g, 38%) as an off-white solid. LCMS m/z (%)=474 (M+H35Cl35Cl, 100), 476 (M+H35Cl37Cl, 81.7), 478 (M+H37Cl37Cl, 11.2). 1H NMR (400 MHz, DMSO-d6) δ: 8.83 (bs, 1H), 8.73 (bs, 1H), 7.61 (s, 1H), 7.54 (dd, J=2.65, 2.69 Hz, 1H), 7.46 (dd, J=2.06, 2.11 Hz, 2H), 7.37 (d, J=2.7 Hz, 1H), 7.31 (dd, J=2.09, 2.04 Hz, 2H), 7.16 (d, J=9.03 Hz, 1H), 4.2-4.0 (bm, 2H), 3.65 (s, 3H), 2.7-2.5 (bm, 2H), 2.4-2.3 (bm, 4H), 1.7-1.5 (bm, 4H).
