실험 절차

To a solution of 6-chloropyridazine-3-carboxylic acid (2-cyclopropyl-2-hydroxyethyl)amide (58 mg, 0.24 mmol) in 10 mL of DMF was added 1,8-diazabicylco[5.4.0]undec-7-ene (0.109 g), piperazin-1-yl-(2-trifluoromethylphenyl)methanone (86.7 mg, 0.33 mmol) and Bu4NI (4 mg, 0.01 mmol). The mixture was heated at 80° C. overnight. Water was added and the mixture was extracted with ethyl acetate (2×15 mL). The organic extract was washed with diluted HCl, followed by bicarbonate solution and brine, then dried over Na2SO4 and concentrated. The residue was dissolved in small amount of dichloromethane and purified by column chromatography eluted with ethyl acetate to yield the product as a white solid (35.5 mg, 32% yield). 1H NMR (300 MHz, CDCl3) δ 8.24, 8.02, 7.73, 7.58, 7.34, 6.98, 4.04, 3.85, 3.52, 3.33, 3.10, 2.60-2.41, 0.95, 0.52, 0.32. MS (ES+) m/z 464.3 (M+1).
