| description | The present invention generally relates to an improved process for preparation of 5- Amino-2,4-di-tert-butylphenol or hydroxyl derivative thereof or an acid addition salt thereof, which is an intermediate of Ivacaftor. More specifically the present invention relates to a process for preparation of hydrochloric acid salt of 5-Arnino-2,4-di-tert- butylphenol.
La présente invention concerne, de façon générale, un procédé amélioré de préparation de 5-amino-2,4-di-tert-butylphénol ou d'un dérivé hydroxylé de celui-ci ou d'un sel d'addition acide de celui-ci, constituant un intermédiaire pour l'ivacaftor. La présente invention concerne, plus précisément, un procédé de préparation du sel d'acide chlorhydrique du 5-amino-2,4-di-tert-butylphénol. |
