Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrochloric Acid | HCID 313 | — |
| Reactant | Sodium 2-(2-pyridinyl)-4-carboxyquinoline carboxylate | HCID 70240266 | — |
| Product | 2-(Pyridin-2-yl)quinoline-4-carboxylic acid | HCID 24103 | — |
Reaction Steps
The free acid is prepared by neutralizing an aqueous solution of the sodium 2-(2-pyridyl)4-carboxyquinoline carboxylate 3 with 10% HCl. The acid is somewhat soluble in acidic solution, and care should be taken not to overacidify; a pH of 7 is optimum. The solid is filtered, washed with 40 mL of acetone and allowed to air dry.
