| titleOfInvention | Method for separating quinaldine isomers |
| abstract | (57) [Problem] To provide a quinaldine isomer having a substituent at the 7-position, Isolate in high purity and high yield. SOLUTION: Do starting from 3-substituted aniline is used as a starting material. To a reaction solution containing a quinaldine isomer obtained by the ebner-Miller method, zinc chloride is added to convert the quinaldine isomer into a hydrochloric acid / zinc chloride complex, and then an aliphatic ketone is added and the precipitated crystals are filtered off. As a result, the 7-substituted quinaldine isomer can be isolated with high purity and high yield. |
