実験手順

To a solution of (4-(6,7-dihydroxy-4-thiaheptanoylamino)benzoyl)glutamic acid di-t-butyl ester as obtained in Reference Example 6 (50 mg) in chloroform (1 ml), triethylamine (0.258 ml), stearyl chloride (0.25 ml) and dimethylaminopyridine (1 mg) were added, followed by stirring at room temperature for 24 hours. After addition of water, the reaction mixture was extracted with ethyl acetate. The extract was washed with a 5% aqueous solution of citric acid, a saturated aqueous solution of sodium hydrogen carbonate and saturated saline, and dried over anhydrous sodium sulfate, and the solvent was distilled off. The resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=2:1) to yield the title compound (75 mg, yield 76%) as a wax-like substance.
