How is Dimethyl 1,3-cyclohexanedicarboxylate (CAS: 62638-06-6) typically synthesized?

Dimethyl 1,3-cyclohexanedicarboxylate is typically synthesized from 1,3-cyclohexanedicarboxylic acid and dimethylformamide as a solvent. The reaction involves the esterification of the carboxylic acid groups with dimethyl sulfate, followed by the removal of the dimethyl sulfate. Commonly used catalysts include sulfuric acid or hydrochloric acid, and the yield is generally around 70-80%. The process is conducted under reflux conditions to ensure complete conversion.
