Vorschrift

A mixture of 6-(2-chlorophenyl)-3-methyl-2-(3-phenylpropyl)-4,5,6,7-tetrahydroindazol-4-one (0.25 g), aminoguanidine hydrochloride (0.11 g), concentrated hydrochloric acid (0.16 ml), water (0.16 ml) and ethanol (15 ml) was refluxed for 8 hours. Under reduced pressure, the solvent was evaporated, and the resulting crystals were recrystallized from ethanol-water to give 6-(2-chlorophenyl)-4-guanidinoimino-3-methyl-2-(3-phenylpropyl)-4,5,6,7-tetrahydroindazole hydrochloride (Compound 154) (0.24 g) as colorless crystals.
