실험 절차

3′-Pyridin-4-ylethynyl-2,3,5,6-tetrahydro-[1,2′]bipyrazinyl-4-carboxylic acid (3,5-bis-trifluoromethylphenyl)amide (˜0.4 mmol) was dissolved in 5 mL ethanol. Then, 50 mg of 10% palladium on carbon was added. The reaction flask was flushed with hydrogen and the reaction was stirred at room temperature for 5 hr under 1 atmosphere of hydrogen. The reaction mixture was filtered through Celite and concentrated under vacuum. The residue was purified by reverse phase HPLC to give N-[3,5-bis(trifluoromethyl)phenyl]-4-{3-[(pyridin-4-ylmethyl)oxy]pyridin-2-yl}piperazine-1-carboxamide (80 mg) as a yellow solid. 1H NMR (DMSO-d6) δ 9.34 (s, 1H), 8.48 (d, 2H), 8.23 (s, 1H), 8.20 (d, 1H), 8.14 (d, 2H), 7.58 (s, 1H), 7.39 (d, 2H), 3.66 (m, 4H), 3.13-3.43 (m, 8H) ppm.
