実験手順

Compound 454 (125 mg, 0.450 mmol) was dissolved in DMF (2 mL), and 4-(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. Water (200 mL) was added to the reaction mixture, and the precipitated solid was collected by filtration. The resulting solid was purified through silica gel column chromatography (chloroform:methanol=9:1), followed by reslurrying with ethanol to afford the entitled Compound 465 (5.30 mg, 3%) as a pale brown solid.
