Participants

Reaction Steps

To a solution prepared by dissolving 300 mg (0.70 mM) of 4,5-dihydro-4-[3-(1-trifluoromethanesulfonyl-piperidin-4-yl)propan-1-yl]-3H-1,4,8b-triazaacenaphthylen-3-one in 10 ml of ethanol was added 0.12 ml (1.4 mM) of 12N hydrochloric acid at room temperature. After stirring, the solvent was distilled off under reduced pressure and 10 ml of 2-propanol was added to the residue. The precipitate that formed was recovered by filtration and rinsed with a small amount of ether to provide 265 mg (yield 81.1%) of the title compound as light-yellow solid.
