To a solution prepared by dissolving 3.71 g (10.0 mM) of 4,5-dihydro-4-(1-tert-butoxycarbonylpiperidin-4-ylmethyl)-3H-1,4,8b-triazaacenaphthylen-3-one in 50 ml of ethanol was added 4.11 ml of 12N-hydrochloric acid at room temperature. This mixture was stirred at room temperature for 1 hour and the resulting precipitate was recovered by filtration.
