실험 절차
To p-fluoro-α-methylcinnamic acid (177.9 g, 0.987 mol) in 3.6 l ethanol is added 11.0 g of 5% Pd/C. The mixture is reduced at room temperature under a hydrogen pressure of 40 p.s.i. When hydrogen uptake ceases, the catalyst is filtered off, and the solvent is evaporated in vacuo to give the product, p-fluoro-α-methylhydrocinnamic acid, which was used directly in the next step.
