Process for preparing pyridine carboxylic acid esters |
| abstract |
A novel method is disclosed for the preparation of 2,3-pyridine-dicarboxylates by the reaction of a ketoester such as dimethyl oxalacetate with an alpha,beta-unsaturated aldehyde or ketone such as 2-ethylacrolein and at least 1 molar equivalent of ammonium salt in suitable solvent and optionally a dehydrogenation catalyst such as palladium on carbon. |
