🔬
3-(1-cyanoethyl)benzoic acid is prepared from methyl 3-cyanomethylbenzoate, which is first reacted with dimethyl carbonate in the presence of potassium carbonate to obtain methyl 3-(1-cyanoethyl)benzoate, which is then hydrolyzed, acidified, crystallized, and purified to obtain 3-(1-cyanoethyl)benzoic acid.
