How is (2-Fluoro-5-methoxyphenyl)acetic acid (CAS: 798563-50-5) typically synthesized?

(2-Fluoro-5-methoxyphenyl)acetic acid can be synthesized using a two-step process. First, 2-fluoro-5-methoxybenzaldehyde is reacted with acetyl chloride in the presence of an appropriate base to form the acetylated product. This is then hydrolyzed using a strong acid to yield the carboxylic acid. The synthesis involves the use of potassium hydroxide as a base and is typically performed in methanol or ethanol. Yield and selectivity are generally high in this process.
