Procedure
40 mg (0.09 mmol) of the compound obtained in Step 2 of Example 223 was dissolved in 1.5 mL of pyridine, and 22 mg (0.14 mmol) of (E)-4-(dimethylamino)-2-butenoic acid hydrochloride and 35 mg (0.18 mmol) of N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride were added thereto, and stirred for 30 minutes at 80° C. Upon the completion of the reaction, the resulting mixture was diluted with mixed solvent of chloroform:2-propanol (3:1(v/v)) and washed with saturated saline. The organic layer was separated, dried over anhydrous Na2SO4, and filtered and distilled under a reduced pressure. The resulting residue was separated by column chromatography (dichloromethane:methanol=6:1 (v/v)) to obtain 2 mg of the title compound (yield: 4%).
