実験手順

3-(2-Aminoethylidene)-4-methoxyindan-5-amine (15.3 mg, 0.076 mmol) and triethylamine (21.2 μL, 0.152 mmol) were dissolved in tetrahydrofuran (0.9 mL), a solution of acetic anhydride (7.18 μL, 0.076 mmol) in tetrahydrofuran (0.1 mL) was added under ice-cooling, and the mixture was stirred for 15 min. To the reaction solution was added saturated aqueous sodium hydrogencarbonate solution. The mixture was extracted with ethyl acetate and washed with saturated brine. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate/methanol=100/0→90/10) to give the title compound (16.2 mg, yield 87%).
