실험 절차

4-{[(2-{2-[(2-tert-Butyl-1,1-dimethyl-2-oxoethyl)thio]-1,3-thiazol-4-yl}ethyl)(5-ethylpyrimidin-2-yl)amino]methyl}benzoic acid methyl ester (2.2 g) synthesized in Example 437-1 was dissolved in methanol (50 mL) and tetrahydrofuran (50 mL), 1N aqueous sodium hydroxide solution (16 ml) was added, and the mixture was stirred at 60° C. for 4 hr. Aqueous 10% citric acid solution was added, and the mixture was extracted with chloroform. The insoluble material was filtered off, and the filtrate was washed with water and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give the title compound (2.0 g) as an oil.
