Procedure

N-[2-(6-Amino-7-hydroxy-2,3-dihydro-1H-inden-1-yl)ethyl]acetamide hydrochloride (251 mg, 0.928 mmol) was dissolved in pyridine (10 mL), (benzyloxy)acetyl chloride (160 μL, 1.01 mmol) was added under ice-cooling, and the mixture was stirred for 15 min. Water was added to the reaction solution, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane=80/20→100/0) to give the title compound (285 mg, yield 80%).
