실험 절차
Pd—C (150 mg, 10%) is added to a solution of a mixture of E/Z isomers of ethyl (1,5,6,7-tetrahydro-1-phenyl-4H-indazol-4-ylidene)acetate (1.6 g, 5.67 mmol) in 50 mL of EtOH, and the resulting solution is stirred under nitrogen atmosphere (50 psi) in a Parr hydrogenator for 18 hours. The reaction mixture is purged with nitrogen, filtered through Celite and the solvent is evaporated under reduced pressure, to obtain ethyl 2-(4,5,6,7-tetrahydro-1-phenyl-1H-indazol-4-yl)acetate (1.60 g, 5.63 mmol, 99%, oil).
