Vorschrift

A mixture of 6-(2-chlorophenyl)-3-methyl-1-(3-phenylpropyl)-4,5,6,7-tetrahydroindazol-4-one (0.11 g), aminoguanidine hydrochloride (0.048 g), concentrated hydrochloric acid (0.073 ml), water (0.073 ml) and ethanol (10 ml) was refluxed for 8 hours. Under reduced pressure, the solvent was evaporated, and the resulting crystals were recrystallized from ethanol to give 6-(2-chlorophenyl)-4-guanidinoimino-3-methyl-1-(3-phenylpropyl)-4,5,6,7-tetrahydroindazole hydrochloride (Compound 153) (0.12 g) as colorless crystals.
