実験手順

Compound 454 (125 mg, 0.450 mmol) was dissolved in DMF (2 mL), and 3-(dimethylamino)benzoic acid (296 mg, 1.80 mmol), EDC hydrochloride (344 mg, 1.80 mmol) and 1-hydroxybenzotriazole monohydrate (276 mg, 1.80 mmol) were added thereto, followed by stirring at 80° C. for 2 hours. The reaction mixture was poured into water (200 mL), followed by extraction with chloroform. The organic layer was washed with water and a saturated aqueous solution of sodium chloride and dried over anhydrous magnesium sulfate, and then the solvent was distilled away under reduced pressure. The resulting residue was purified through silica gel column chromatography (chloroform:methanol=19:1), followed by reslurrying with methanol to afford the entitled Compound 464 (78.5 mg, 41%) as a pale yellow solid.
