Participants

Reaction Steps

Into the solution of compound 8 (12.3 g, 0.058 mol) in trans-decahydronaphthalene (trans-decalin) was added 10% Pd/C (2.7 g), and the mixture was heated under reflux for 4 h, and then concentrated in vacuo in oil bath until there were about 20 mL solution left. Petroleum ether (80 mL) was added into the residue while hot, and the mixture was well mixed by shaking. The mixture was allowed to precipitate upon cooling to afford 3-(4-methylphenyl)-1H-indazole (10, 9.85 g, 82% yield).
