The reaction of 5-acetyl-4-aryl-6-hydroxy-3,6-dimethyl-4,5,6,7-tetrahydroindazoles p-toluenesulfonyl chloride in boiling acetone in the presence of triethylamine was found to occur in a completely regioselective with the exclusive formation of 5-acetyl-4-aryl-6-hydroxy-3,6-dimethyl-1-(4-methylbenzenesulfonyl)-4,5,6,7-tetrahydroindazoles. The experimental results were confirmed by quantum chemical calculations. In silico biological activity evaluation of the synthesized compounds was performed.
