実験手順
To a stirred solution of compound 5-(5-(trifluoromethyl)-1,2,4-oxadiazol-3-yl)nicotinic acid (100 mg, 0.4 mmol) in dry DMF (5 mL) were added HATU (180 mg, 0.46 mmol) followed by hydrochloride salt of (4-(4-phenylthiazol-2-yl)tetrahydro-2H-pyran-4-yl)methanamine (120 mg, 0.4 mmol) and NMM (0.12 mL, 1.1 mmol) at 0° C. The reaction mixture was slowly warmed to room temperature and stirred for further 10 h. The reaction mixture was diluted with EtOAc. The organic layer was washed with water and brine solution, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The crude product was purified by column chromatography (silica 60-120 mesh, eluent 50-60% EtOAc in petroleum ether) to get pure product N-((4-(4-phenylthiazol-2-yl)tetrahydro-2H-pyran-4-yl)methyl)-5-(5-(trifluoromethyl)-1,2,4-oxadiazol-3-yl)nicotinamide (70 mg, yield 37%): 1H NMR (400 MHz, CDCl3) δ 9.43 (d, J=2 Hz, 1H), 9.21 (br s, 1H), 8.76 (br s, 1H), 7.87 (d, J=7 Hz, 2H), 7.75 (br s, 1H), 7.53 (s, 1H), 7.41-7.32 (m, 3H), 3.99-3.95 (m, 2H), 3.79-3.74 (m, 2H), 2.35-2.32 (m, 2H), 2.07-2.03 (m, 2H). MS (ESI) m/z: Calculated for C24H20F3N5O3S: 515.12. found: 516.0 (M+H)+.
