Reaction Steps

Following the procedure for 3-(7-fluoro-4-trifluoromethylbenzothiazol-2-yl)-5-(1-piperidin-4-yl-1H-pyrazol-4-yl)-pyridin-2-ylamine, using 5-fluoro-2-iodo-1,3-benzothiazole and conducting the Suzuki coupling at 55° C. for 3 h, the title compound was obtained as a yellow solid. 1H NMR (400 MHz, DMSO-d6): δ=9.20-9.09 (brm, 1H), 9.04-8.92 (brm, 1H), 8.71 (very brs, 1H), 8.58 (d, J=2.0 Hz, 1H), 8.55 (brs, 1H), 8.47 (s, 1H), 8.28 (dd, J=5.2, 9.0 Hz, 1H), 8.10 (s, 1H), 8.01 (dd, J=2.6, 9.4 Hz, 1H), 7.47 (dt, J=2.4, 9.0 Hz, 1H), 4.58-4.48 (mc, 1H), 3.40 (brd, J=12.5 Hz, 2H), 3.11 (brq, J=12.0 Hz, 2H), 2.30-2.12 (m, 4H). MS(ES+): m/z=395.09 (73) [MH+], 312.05 (100) [MH+-piperidine]. HPLC: tR=2.06 min (polar—5 min, ZQ2).
