| | Diethyl 2,6-pyridinedicarboxylate Usage And Synthesis |
| Chemical Properties | Yellow to red crystalline powder | | Synthesis | Pyridine-2,6-dicarboxylic acid (10.0g, 59.9mmol) was added into ethanol (120mL),
then 3 drops of concentrated sulfuric acid were added. The mixture was heated to
reflux for 8 hours. After evaporation of the solvent, the solid residue was washed with
saturated Na2CO3 aqueous solution and extracted with chloroform for 3 times. The
organic phase was dried with small amount of MgSO4. The solvent was removed to
afford 1 as white powder (12.6g, 56.3mmol, yield = 94%). 1
