反応手順
A suspension of 100 g of p-(2-chlorophenyl)cinnamic acid in 1 l. of 95% ethanol is hydrogenated at atmospheric pressure using platinum oxide catalyst (1 g). The uptake of hydrogen ceases when approximately 9-10 l. of hydrogen is consumed. The catalyst is then filtered off and the reaction evaporated to dryness to give β-(2'-chloro-4-biphenylyl)propionic acid.
