Reaction Steps

N-[2-(6-Amino-7-hydroxy-2,3-dihydro-1H-inden-1-yl)ethyl]acetamide hydrochloride (100 mg, 0.369 mmol) was dissolved in pyridine (4 mL), cyclopropylcarbonyl chloride (36.8 μL, 0.406 mmol) was added under ice-cooling, and the mixture was stirred for 3 hr. 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/methanol=100/0→95/5) to give the title compound (119 mg, yield 100%).
