실험 절차

2-(5-Fluoro-2-methyl-6,7-dihydrocyclopenta[e]indazol-8(2H)-ylidene)ethanamine (78.0 mg, 0.337 mmol) was dissolved in tetrahydrofuran (3.4 mL), triethylamine (56.4 μL, 0.404 mmol) and acetic anhydride (35.0 μL, 0.371 mmol) were added under ice-cooling, and the mixture was stirred for 15 min. The reaction solution was diluted with saturated aqueous sodium hydrogen carbonate solution, diluted with ethyl acetate, washed with water and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The obtained crystals were washed with diisopropyl ether to give the title compound (82.0 mg, yield 89%).
