반응 단계
In an atmospheric pressure hydrogenation equipment 10.0 g (60.9 mM) of 3,4-dimethoxystyrene, 0.5 g of palladium charcoal and 200 ml of methanol were charged and introduced with hydrogen. The reaction was continued until the absorption of hydrogen was terminated. Palladium charcoal was filtered off from the reaction mixture. Methanol was distilled off from the filtrate. The residue was distilled under vacuum to obtain 10.0 g (60.2 mM) of 4-ethylveratrole as a colorless transparent liquid having a boiling point of 84°-85° C./2 mmHg
