実験手順
Compound 610 (102 mg, 0.366 mmol) was dissolved in DMF (3 mL), and 3-pyridylacetic acid hydrochloride (635 mg, 3.66 mmol), EDC hydrochloride (702 mg, 3.66 mmol), 1-hydroxybenzotriazole monohydrate (561 mg, 3.66 mmol) and triethylamine (0.510 mL, 3.66 mmol) were added thereto, followed by stirring at 80° C. for 10 hours. The reaction mixture was poured into a saturated aqueous solution of sodium hydrogencarbonate, and the precipitated solid was collected by filtration. The resulting solid was purified through silica gel column chromatography (hexane:ethyl acetate=2:1), followed by recrystallizing from a mixed solvent of ethanol and water to afford the entitled Compound 618 (74.6 mg, 52%) as a white solid.
