How is (3,4-Difluorophenyl)(hydroxy)acetic acid (CAS: 132741-29-8) typically synthesized?

(3,4-Difluorophenyl)(hydroxy)acetic acid (CAS: 132741-29-8) can be synthesized through a multi-step process involving the reaction of 3,4-difluorophenol with acetic anhydride, followed by hydrolysis. This method typically yields a product with a purity of over 95%. Commonly, this synthesis is carried out in the presence of a catalyst, such as hydrochloric acid, to increase selectivity and yield. Proper safety measures should be taken during the reaction, including the use of fume hoods and appropriate personal protective equipment.
