Procedure

To a solution of ethyl 3-(2-fluoro-4-{[4-(1-hydroxybutyl)benzyl]oxy}phenyl)propanoate (0.500 g, 1.34 mmol), 2-mercapto-4-phenylthiazole (0.284 g, 1.47 mmol) and triphenylphosphine (0.700 g, 2.67 mmol) in toluene (10 mL) was added diethyl azodicarboxylate (40% toluene solution, 1.21 mL, 2.67 mmol) with stirring at room temperature, and the mixture was stirred at the same temperature for 1.5 hr. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate:hexane=0:100-20:80) to give the title compound (0.555 g, yield 76%) as a colorless oil.
