실험 절차
To a solution prepared by dissolving 2.12 g (5.51 mM) of 4,5-dihydro-4-[3-(1-tert-butoxycarbonylpiperidin-4-yl)propan-1-yl]-3H-1,4,8b-triazaacenaphthylen-3-one in 30 ml of ethanol was added 1.40 ml of 12N-hydrochloric acid and the mixture was stirred at room temperature for 1 hour. After completion of the reaction, the solvent was distilled off under reduced pressure. To the residue was added 5 ml of ethanol and 5 ml of ether and the resulting precipitate was recovered by filtration. The precipitate was rinsed with small amounts of ethanol and ether to provide 1.87 g (yield 91.2%) of the title compound as light-yellow crystals.
