Versuchsvorschrift

A mixture of 2,4-dimethyl-7-(2-pyridyl)-5,6,7,8-tetrahydroquinolin-5-one (0.08 g), aminoguanidine hydrochloride (0.037 g), concentrated hydrochloric acid (0.079 ml), water (0.079 ml) and ethanol (10 ml) was refluxed for 7 hours. Under reduced pressure, the solvent was evaporated, and the residue was dissolved in water. The solution was washed with ethyl acetate. Under reduced pressure, the solvent was evaporated, and the residue was recrystallized from water-ethanol to give 5-guanidinoimino-2,4-dimethyl-7-(2-pyridyl)-5,6,7,8-tetrahydroquinoline hydrochloride (Compound 87) (0.1 g) as colorless crystals.
