실험 절차

Compound 454 (834 mg, 3.00 mmol) was dissolved in DMF (12 mL), and 4-fluorobenzoic acid (3.36 g, 24.0 mmol), EDC hydrochloride (4.12 g, 24.0 mmol) and 1-hydroxybenzotriazole monohydrate (3.68 g, 24.0 mmol) were added thereto, followed by stirring at 80° C. for 2 hours. The reaction mixture was poured into a mixture of a saturated aqueous solution of sodium hydrogencarbonate (30 mL) and water (30 mL), and the precipitated solid was collected by filtration. The resulting solid was purified through silica gel column chromatography (chloroform:methanol=19:1), followed by recrystallizing from ethanol to afford the entitled Compound 468 (270 mg, 23%) as a white solid.
