実験手順
N-[2-(6-Amino-7-hydroxy-2,3-dihydro-1H-inden-1-yl)ethyl]acetamide hydrochloride (162 mg, 0.600 mmol) was dissolved in pyridine (10 mL), 5-(benzyloxy)pentanoyl chloride (150 mg, 0.662 mmol) was added under ice-cooling, and the mixture was stirred 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 (105 mg, yield 41%).
