実験手順

4-(Benzyloxy)pentanoic acid (230 mg, 1.10 mmol) was dissolved in tetrahydrofuran (10 mL), oxalyl chloride (90 μL, 1.05 mmol) and dimethylformamide (10 μL) were added under ice-cooling, and the mixture was stirred for 30 min. The solvent was evaporated under reduced pressure, and the residue was diluted with dichloromethane (1 mL). This was added to a solution of N-[2-(6-amino-7-hydroxy-2,3-dihydro-1H-inden-1-yl)ethyl]acetamide hydrochloride (244 mg, 0.903 mmol) in pyridine (10 mL) under ice-cooling, and the mixture was stirred at room temperature for 15 min. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate/hexane=80/20→100/0) to give the title compound (220 mg, yield 57%).
