참여 물질

반응 단계

To a solution of ethyl 4'-methylbiphenyl-3-carboxylate (4.0 g) in ethanol (50 ml) was added a solution of 10 ml of 10% aqueous sodium hydroxide, and the mixture refluxed for 2 hours. Solvent was removed under reduced pressure, water added to the residue, and the solution filtered. The filtrate was acidified with dilute hydrochloric acid, and the white solid filtered off and dried under vacuum, yielding 2.4 g of 4'-methylbiphenyl-3-carboxylic acid m.p. 192° C.
