Method of preparing tertiary alcohol |
| abstract |
Tertiary alcohols are prepared by reacting a carboxyl ester with Grignard reagent in an ethereal solvent in the presence of lanthanum trichloride and lithium chloride. This method is particularly effective for (αS) -α- [3-[(1E) -2- (7-chloro-2-quinolinyl) ethenyl] phenyl]-of formula (A), which is an intermediate in the production of montelukast. Suitable for the preparation of 2- (1-hydroxy-1-methylethyl) benzenepropanol: . |
