실험 절차

To a solution of 3′-chloro-2,3,5,6-tetrahydro-[1,2′]bipyrazinyl-4-carboxylic acid (3,5-bis-trifluoromethyl-phenyl)-amide (115 mg, 0.254 mmol) and 1M solution of potassium tert-butoxide in tert-butanol (0.80 mL, 0.80 mmol) was added 2-Chloro-4-pyridinemethanol (81.8 mg, 0.568 mmol). The resulting suspension was stirred at room temperature for 15 h. The crude reaction mixture was diluted with methanol and purified by preparative HPLC (50 mM NH4OAc(aq), Acetonitrile system). The product was isolated by lyophilization of pure fractions yielding N-[3,5-bis(trifluoromethyl)phenyl]-4-(3-{[(2-chloropyridin-4-yl)methyl]oxy}pyrazin-2-yl)piperazine-1-carboxamide (29.9 mg, 21% yield). 1H NMR (CDCl3) 8.41 (d, 1H), 7.91 (s, 2H), 7.82 (d, 1H), 7.61 (d, 1H), 7.54 (s, 1H), 7.39 (s, 1H), 6.70 (s, 1H), 5.47 (s, 2H), 3.70-3.65 (m, 8H) ppm.
