실험 절차

To a solution of 2-(3-ethoxy-buta-1,3-dienyl)-5-hydroxy-benzonitrile (600 mg) in EtOAc (50 mL) was added 5% Pd/C (0.3 g). The reaction was exposed to hydrogen gas in a Parr apparatus at 60 psi overnight at ambient temperature. The reaction mixture was filtered and concentrated to give the title compound (410 mg). MS [EI] m/z 218 (M+H)+.
