Reaction Steps
A mixture of 3-(2-methyl-2H-pyrazol-3-yl)-4-(2-pyrrolidin-1-yl-ethoxy)-phenylamine (100 mg, 0.35 mmol), 4-chloromandelic acid (98 mg, 0.525 mmol), HATU (200 mg, 0.525 mmol) and triethylamine (0.5 mL) in DMF (6 mL) was heated at 50° C. overnight. The crude was purified by HPLC to provide the title compound as a semi-solid (24 mg, 15%). 1H NMR (DMSO-d6, 400 MHz) δ 1.60-1.73 (m, 2H), 1.84-1.91 (m, 2H), 2.80-2.90 (m, 2H), 3.22-3.30 (m, 4H), 3.65 (s, 3H), 4.25 (t, J=5.05 Hz, 2H), 6.26 (d, J=1.77 Hz, 1H), 7.17 (d, J=9.09 Hz, 1H), 7.39-7.46 (m, 2H), 7.51-7.53 (m, 3H), 7.67 (d, J=2.53 Hz, 1H), 7.80 (dd, J=2.78, 8.84 Hz, 1H), 9.50 (s br, 1H), 10.0 (s, 1H). Exact mass calculated for C24H27ClN4O3 454.2, found 455.4 (MH+).
