| titleOfInvention | PROCESS FOR PREPARATION OF MONTELUKAST AND PRECURSORS OF THE SAME. |
| abstract | Process for preparation of montelukast andnprecursors of it.n n n The present invention provides a processnto stereoselectively reduce acid methyl estern2- [3- [3- [2- (7-Chloro-2-quinolinyl) -etenyl] phenyl] -3-oxopro-pil] benzoic,nin order to producen2- [3- (S) - [3- [2- (7-Chloro-2-quinolinyl) -etenyl] phenyl] -3-hydroxypropyl] benzoaten of methyl, and a process to produce montelukast or a salt ofnsame. The present invention further provides a processnto purifyn2- [3- (S) - [3- [2- (7-Chloro-2-quinolinyl) -etenyl] phenyl] -3-hydroxypropyl] benzoatenof methyl The reduction process of the present invention usesna chiral reagent and can provide the reduction productndesired with a high enantiomeric excess (ee). |
