Participants

Reaction Steps

2-{[4-(2-hydroxyethyl)-1,3-thiazol-2-yl]thio}-2-methylpropionic acid tert-butyl ester (3.0 g) synthesized in Example 4 and 4-bromo-2-fluorophenol (1.91 g) were dissolved in tetrahydrofuran (20 mL), triphenylphosphine (2.62 g) and diethyl diazodicarboxylate (1.74 g) were added under ice-cooling, and the mixture was stirred at room temperature for 6 hr. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel chromatography (elution solvent; hexane:ethyl acetate=6:1) to give the title compound (3.2 g) as a colorless oil.
