Procedure

A mixture of 1-benzoyl-6-phenyl-4,5,6,7-tetrahydroindol-4-one (0.68 g), aminoguanidine hydrochloride (0.26 g), concentrated hydrochloric acid (0.11 ml), water (0.11 ml) and ethanol (50 ml) was refluxed for 30 minutes. Under reduced pressure, the solvent was evaporated, and the residue was washed with water to give crystals, which were recrystallized from ethanol to give 1-benzoyl-4-guanidinoimino-6-phenyl-4,5,6,7-tetrahydroindole hydrochloride (Compound 11) (0.83 g) as colorless crystals.
