実験手順

2-[(4-{2-[(5-Ethylpyrimidin-2-yl)amino]ethyl}-1,3-thiazol-2-yl)thio]-2-methylpropionic acid tert-butyl ester (4.0 g) synthesized in Example 265-1 and 1-bromo-4-(bromomethyl)benzene (2.94 g) were dissolved in N,N-dimethylformamide (40 mL), potassium tert-butoxide (1.32 g) was added thereto, and the mixture was stirred at room temperature 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=4:1) to give the title compound (4.65 g) as a colorless oil.
