| titleOfInvention | Method for preparing fexofenadine |
| abstract | Preparation of fexofenadine comprising purifying 4- [4-chloro-1-oxobutyl] -2,2-dimethylphenylacetic acid alkyl ester by suspending it in a hydrocarbon, preferably n-heptane Describes how to do this. The compound thus obtained is dissolved in a suitable solvent and condensed with azacyclanol, and the following formula (I) (R is an alkyl radical) is produced, and this compound is then hydrolyzed and reduced to give fexofenadine. |
