Reaction Steps

A mixture of 7-phenyl-1,2,5,6,7,8-hexahydroquinoline-2,5-dione (0.19 g), aminoguanidine hydrochloride (0.092 g), concentrated hydrochloric acid (0.04 ml), water (0.04 ml) and ethanol (20 ml) was refluxed for 1 hour. Under reduced pressure, the solvent was evaporated, and the residue was recrystallized from ethanol to give 5-guanidinoimino-7-phenyl-1,2,5,6,7,8-hexahydroquinolin-2-one hydrochloride (Compound 99) (0.21 g) as colorless crystals.
