Procedure

A mixture of ((2S,3R)-2-(aminomethyl)-3-methylpiperidin-1-yl)(5-methyl-2-(1-methyl-1H-pyrazol-4-yl)phenyl)methanone (0.282 g, 0.864 mmol) and 2-fluoro-5-(trifluoromethyl)pyridine (0.29 g, 1.728 mmol) and anhydrous K2CO3 (0.24 g, 1.73 mmol) in DMF (10 mL) was heated at 100° C. overnight. The mixture was cooled to rt and the solvent was removed in vacuo. The crude was dissolved in EtOAc and washed with satd. NaHCO3, brine, and dried (MgSO4). The solvent was removed and the crude was purified by chromatography on silica gel (EtOAc/hexanes) to afford the title compound. 1H NMR (CDCl3, 400 MHz) δ 8.31-8.32 (m, 1H), 7.63-7.53 (m, 4H), 7.26-7.14 (m, 2H), 6.53-6.50 (m, 1H), 4.20-4.11 (m, 1H), 3.92 (s, 3H), 3.60-3.25 (m, 2H), 3.01-2.94 (m, 1H), 2.38 (s, 1H), 2.22 (s, 2H), 1.45-1.22 (m, 4H), 1.04 (d, J=7.0 Hz, 3H), 0.73-0.44 (m, 1H); ESI-MS (m/z): 472 [M+1]+.
