참여 물질

반응 단계

To ρ-fluoro-α-methylcinnamic acid (177.9 g., 0.987 mole) in 3.6 l. ethanol is added 11.0 g. of 5% Pd/C and the mixture is reduced at room temperature under a hydrogen pressure of 40 p.s.i. Uptake is 31/32 lbs. (97% of theoretical). After filtering the catalyst, the filtrate is concentrated in vacuo to give the product ρ-fluoro-α-methylhydrocinnamic acid used without weighing in next step.
