Reaction Steps

A mixture of 4-[2-(4-fluoro-piperidin-1-yl)-ethoxy]-3-(2-methyl-2H-pyrazol-3-yl)-phenylamine (80 mg, 0.25 mmol), 4-fluoro-3-chlorobenzoyl chloride (48 mg, 0.25 mmol), and triethylamine (0.3 mL) in THF (3 mL) was stirred at r.t. for 10 min. The solvent was concentrate in vacuo and the crude was purified by HPLC to give the title compound (58 mg, 50%) as a white solid as TFA salt. 1H NMR (acetone-d6, 400 MHz) δ 2.02-2.24 (m, 4H), 3.08-3.18 (m, 2H), 3.32-3.42 (m, 2H), 3.63 (t, J=4.55 Hz, 2H), 3.80 (s, 3H), 4.59 (t, J=4.55 Hz, 2H); 4.91-5.03 (m, 1H), 6.30 (d, J=1.77 Hz, 1H), 7.23 (d, J=8.84 Hz, 1H), 7.43-7.51 (m, 2H), 7.81 (t, J=2.27 Hz, 1H), 7.91-7.97 (m, 1H), 8.02-8.08 (n, 1H), 8.18 (dd, J=2.53, 7.33 Hz, 1H), 9.71 (s, 1H). Exact mass calculated for C24H25ClF2N4O2 503.1. found 504.1/506.1 (MH+).
