실험 절차

To a mixture of 6-{4-[2-(trifluoromethyl)phenoxy]piperidin-1-yl}pyridazine-3-carboxylic acid (250 mg, 0.7 mmol), HOBt (92 mg, 0.7 mmol), HATU (518 mg, 1.4 mmol) and ammonium chloride (74 mg, 1.4 mmol) in DMF (5 mL) was added N,N-diisopropylethylamine (592 μL, 3.4 mmol) at room temperature. The mixture was stirred at room temperature overnight, diluted with water and extracted with EtOAc. The organic extract was washed twice with 1N NaOH, brine, dried (Na2SO4) and concentrated. CombiFlash chromatography (10 g, 80-100% EtOAc in hexanes, 20 mL/min, 18 mL/fraction) gave the title compound as a white powder. 1H NMR (400 MHz, acetone-d6): δ 1.93-1.99 (m, 2H), 2.14-2.20 (m, 2H), 3.93-4.09 (m, 4H), 5.05 (s, 1H), 6.72 (s, 1H), 7.13 (t, 1H), 7.38 (m, 2H), 7.62-7.68 (m, 2H), 7.84 (s, 1H), 7.94 (d, 1H). MS (+ESI) m/z 367 (MH+).
