Versuchsvorschrift

3,4-Dihydro-1(2H)-quinolinamine hydrochloride (5.0 g, 27 mmol) and 1,3-cyclohexanedione (3.1 g, 27 mmol) was mixed in AcOH (4.3 mL) and H2O (4.3 mL). The mixture was heated at 40° C. for 10 min until dissolved completely. The mixture was then concentrated to dryness. The residue was washed with acetonitrile then filtered to yield 3-(3,4-dihydro-1(2H)-quinolinylimino)-1-cyclohexen-1-ol hydrochloride (5.2 g, 69%) as a yellow solid.
