| titleOfInvention | Synthetic method of Montelukast sodium intermediate |
| abstract | It aims at providing the synthesis method of the montelukast sodium intermediate suitable for mass production. To achieve this object, the present invention provides a montelukast sodium intermediate 2- (2- (3- (2- (7-chloro-2-quinolinyl) ethenyl) phenyl)-suitable for large scale production. A process for the preparation of 3-oxopropyl) phenyl) propyl alcohol is provided. In this production method, 7-chloroquinaldine and 3-cyanobenzaldehyde are condensed as starting materials, and then reacted with a halogenated compound 2- (2-o- (2-halogenated ethyl) phenylpropyl) tetrahydropyran ether. It is characterized by that. [Selection figure] None |
