Compound 1 (50 mg) and succinic acid monoethyl ester chloride (51 μL) were dissolved in pyridine (1 mL), followed by stirring for a whole day and night. After completion of reaction, the resultant reaction mixture was concentrated to dryness under reduced pressure, followed by purification by means of silica gel chromatography employing a chloroform/methanol system, to thereby produce the target product (73 mg, yield: 90%).
