Methods for the preparation of phenoxypropionic acid derivatives |
| abstract |
D (+) - 2- [4- (6-chloro-2-quinoxalyloxy) -phenoxy] -propionic acid and its esters are prepared by the methods of the invention by reacting 4- (6-chloro-2-quinoxalyloxy) ) -phenol is reacted with an L-2-chloropropionic acid in an aromatic hydrocarbon solvent in the presence of an aprotic polar solvent, and the resulting alkali metal salt of D (+) - 2- [4- (6-chloro-2-quinoxalyloxy) -phenoxy] -propionic acid is treated with an acid. and optionally converting the resulting propionic acid to its ester.
