実験手順

{2-[(2-tert-Butoxy-1,1-dimethyl-2-oxoethyl)thio]-1,3-thiazol-4-yl}acetic acid (25.0 g) synthesized in Example 3 and heptylamine (10.0 g) were dissolved in dichloromethane (250 mL), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide (EDC) hydrochloride (18.0 g) and hydroxybenzotriazole (HOBT) monohydrate (16.6 g) were successively added thereto, and the mixture was stirred at room temperature for 5 hr. Water was added to the reaction mixture, and the mixture was extracted with dichloromethane. 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=2:1) to give the title compound (30.0 g) as a slightly yellow oil.
