Vorschrift

A mixture of 6-(2-chlorophenyl)-3-methyl-1-(2-phenylethyl)-4,5,6,7-tetrahydroindazol-4-one (0.15 g), aminoguanidine hydrochloride (0.055 g), concentrated hydrochloric acid (0.1 ml), water (0.1 ml) and ethanol (15 ml) was refluxed for 12 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-(2-phenylethyl)-4,5,6,7-tetrahydroindazole hydrochloride (Compound 151) (0.07 g) as colorless crystals.
