How is Ethyl 2-(4-chlorophenoxy)-2-methylpropanoate (CAS: 637-07-0) typically synthesized?

Ethyl 2-(4-chlorophenoxy)-2-methylpropanoate (CAS: 637-07-0) is typically synthesized via an esterification reaction using 2-(4-chlorophenoxy)-2-methylpropanol and ethyl chloroformate in the presence of a base like triethylamine. The reaction is carried out in an organic solvent such as dichloromethane or toluene. The product is isolated by crystallization and can be further purified by recrystallization or chromatography. The yield is generally around 70-80%, and the reaction is selective with good control over the desired product.
