실험 절차

2-(5-methyl-2-phenyloxazol-4-yl)ethylbromide (136 mg) and 3-mercaptophenylacetic acid.methyl ester (78 mg) were dissolved in acetonitrile (5 ml) and thereto was added potassium carbonate and the mixture was stirred at room temperature for 1 hour. The reaction mixture was poured into ice water and the mixture was extracted with ether. The extract was washed with an aqueous solution of sodium hydroxide, water and a saturated aqueous solution of sodium chloride, successively, dried over anhydrous magnesium sulfate and concentrated. The residue was purified by column chromatography on silica gel (chloroform:ethyl acetate=200:1→50:1) to give the compound of the present invention (92 mg) having the following physical data.
