実験手順

Under nitrogen atmosphere, 2-[(4-{2-[(4-bromobenzyl)oxy]ethyl}-1,3-thiazol-2-yl)thio]-2-methylpropionic acid ethyl ester (0.9 g) synthesized in Example 155-2 and 4-fluorophenylboric acid (425 mg) were dissolved in dioxane (10 mL) and aqueous sodium carbonate solution (2 mol/L, 5 mL), tetrakis(triphenylphosphine)palladium (117 mg) was added, and the mixture was refluxed for 4 hr. The reaction mixture was cooled, water was added thereto, 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=5:1) to give the title compound (400 mg) as a colorless oil.
