Procedure

A mixture of N-[4-(2-bromo-ethoxy)-3-(2-methyl-2H-pyrazol-3-yl)-phenyl]-3-fluoro-benzamide (104 mg, 0.25 mmol), 4,4-difluoropiperidine hydrochloride (43 mg, 0.275 mmol) and potassium carbonate (103 mg, 0.75 mmol) in DMF (2 mL) was heated in microwave at 120° C. for 20 min. The crude was purified by HPLC to give the title compound (20 mg, 18%) as a white solid as TFA salt. 1H NMR (DMSO-d6, 400 MHz) δ 2.10-2.23 (m, 4H), 3.10-3.40 (m, 4H), 3.57 (t, 2H), 3.68 (s, 3H), 4.37 (t, 2H), 6.30 (d, 1H), 7.25 (d, 1H), 7.45 (dt, 1H), 7.50 (d, 1H), 7.57-7.62 (m, 1H), 7.72 (d, 1H), 7.74-7.82 (m, 2H), 7.89 (dd, 1H), 10.3 (s, 1H). Exact mass calculated for C24H25F3N4O2 458.2. found 459.4 (MH+).
