실험 절차
2-{[4-(2-Aminoethyl)-1,3-thiazol-2-yl]thio}-2-methylpropionic acid tert-butyl ester (5.0 g) synthesized in Example 7 and 3,6-dichloropyridazine (4.92 g) were dissolved in N-methylpyrrolidone (25 mL), diisopropylethylamine (4.27 g) was added, and the mixture was heated at 130° C. with stirring for 8 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography (elution solvent; hexane:ethyl acetate=2:1 to 1:1) to give the title compound (5.5 g) as a white solid.
