Synthesis
67-56-1
1141-38-4
840-65-3
To a round bottom flask was added 20 g of 2,6-naphthalenedicarboxylic acid dissolved in 150 mL of methanol and 15 mL of concentrated sulfuric acid was added as a catalyst. The reaction mixture was heated to reflux for 24 hours to complete the esterification reaction. Upon completion of the reaction, the mixture was slowly poured into 500 mL of ice water to quench the reaction. The resulting white precipitate was collected by diafiltration and washed with plenty of water to remove residual acid and methanol. Finally, the product was dried in a vacuum drying oven to give 20 g of dimethyl 2,6-naphthalenedicarboxylate in 89% yield.
