HCID 67021327, compound → 2-benzyl-7-isopropyl-3-phenyl-2H-indazole

Participants

Reaction Steps

Thirty milligrams (30 mg; 0.092 mmol) of 2-benzyl-7-isopropenyl-3-phenyl-2H-indazole (Example 521) were dissolved in 2 ml of dry ethanol followed by the addition of 30 mg of PtO2. The reaction mixture was stirred under H2 atmosphere at room temperature for 2 hours, then filtered and the EtOH evaporated. Flash column chromatography (SiO2, dichloromethane/heptane, 1:1, as an eluant) afforded 2-benzyl-7-isopropyl-3-phenyl-2H-indazole in 80% yleld.
