Procedure

To a solution of 4-guanidinoimino-6-(2-chlorophenyl)-3-methyl-4,5,6,7-tetrahydroindazole (0.3 g) in ethanol (10 ml) was added sulfuric acid (0.053 ml), and the mixture was concentrated. The resulting crystals were recrystallized from water-ethanol to give 4-guanidinoimino-6-(2-chlorophenyl)-3-methyl-4,5,6,7-tetrahydroindazole sulfate (Compound 24) (0.29 g).
