Hydrochloric Acid → 1,2-Dihydro-1-[2-(piperidin-4-yl)ethan-1-yl)-1,4,7b-triazacyclopent[cd]inden-2-one dihydrochloride

Participants

Reaction Steps

To a solution prepared by dissolving 5.30 g (14.13 mM) of 1,2-dihydro-1-[2-(1-(tert-butoxycarbonyl)piperidin-4-yl)ethan-1-yl]-1,4,7b-triazacyclopent[cd]inden-2-one in 50 ml of ethanol was added 5.88 ml (71.53 mM) of 12N-hydrochloric acid and the mixture was stirred at room temperature for 1 hour. After completion of the reaction, the reaction mixture was concentrated under reduced pressure and the crystals that formed were collected by filtration and rinsed with small amounts of ethanol and ether to provide 3.51 g (yield of 71.5%) of the title compound as white crystals.
