Versuchsvorschrift

A mixture of 1-methanesulfonyl-3-methyl-6-phenyl-4,5,6,7-tetrahydroindol-4-one (0.41 g), aminoguanidine hydrochloride (0.16 g), concentrated hydrochloric acid (0.068 ml), water (0.068 ml) and ethanol (30 ml) was refluxed for 20 minutes. The reaction solution was allowed to stand in a refrigerator for 12 hours, and precipitated crystals were filtered, which were washed with ethanol and recrystallized from water to give 4-guanidinoimino-1-methanesulfonyl-3-methyl-6-phenyl-4,5,6,7-tetrahydroindole hydrochloride (Compound 13) (0.25 g) as colorless crystals.
