| Product | [2,4'-Bipyridine]-3-carboxylic acid dihydrochloride | HCID 84819756 | — |
Reaction Steps
A solution of ethyl 2,4′-bipyridine-3-carboxylate (14.1 g) in 6 N hydrochloric acid (200 mL) was heated under reflux overnight. The solvent was evaporated under reduced pressure, to the obtained residue was added toluene, and the solvent was again evaporated under reduced pressure to give the title compound (16.4 g).
