Title
(EN) Process for preparing 3,3-diarylpropylamines
Abstract
(EN)

Described is a process of preparing a pure solid or crystalline racemic 3,3-diarylpropylamine compound and the compounds formed thereof. The solid and crystalline forms of racemic 3,3-diarylpropylamine compound are especially suitable for producing highly pure 3,3-diarylpropylamine salts such as tolterodine tartrate. Also described are the highly pure solid or crystalline forms of racemic tolterodine, racemic tolterodine salt and tolterodine tartrate.
