How is Methyl 5-chloro-2,2-dimethylpentanoate (CAS: 73441-42-6) typically synthesized?

Methyl 5-chloro-2,2-dimethylpentanoate (CAS: 73441-42-6) is typically synthesized by the reaction of 2,2-dimethylpentanoyl chloride with methyl alcohol in the presence of an acidic catalyst, such as sulfuric acid. The reaction is conducted at room temperature, and the product is isolated by distillation. The yield is generally around 85-90%, and the selectivity towards the desired product is high.
