Versuchsvorschrift

To a dimethylformamide (5 ml) solution of the compound (208 mg) prepared in Example 2 and 2-aminooxy-2-methoxypropane (57.7 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (115 mg), 1-hydroxybenzotriazole (81 mg) and triethylamine (83 μl ) were added, followed by stirring at room temperature overnight. The reaction mixture was concentrated. The residue was diluted with methylene chloride. The diluted solution was washed with 1N hydrochloric acid, a saturated aqueous sodium hydrogen carbonate solution and saturated saline in this order, dried with anhydrous sodium sulfate, and concentrated. The residue was purified by silica gel column chromatography (chloroform:methanol=50:1) to thereby obtain the title compound (239 mg) having the following physical data.
