Abstract

L'invention concerne plusieurs procédés et composés associés à la darifénacine et/ou à ses sels. L'invention concerne par exemple un procédé de préparation d'une base libre de darifénacine : Formule ou de son sel. Le procédé comprend la mise en réaction de la 3-(S)-(cyanodiphénylméthyl)-1-[2-(2,3-dihydrobenzofuran-5-yl)éthyl] pyrrolidine de formule (IV) ou un de ses sels : Formule (IV) avec une base efficace pour transformer le groupement nitrile du composé de formule (IV) en groupement amide de la darifénacine dans un solvant organique, à condition que le solvant ne soit pas le 2-méthyl-butan-2-ol et que la réaction produise une quantité inférieure à environ 0,5 % du composé de formule (Ic) : Formule (Ic) dans la masse réactionnelle, telle que mesurée par HPLC. L'invention concerne également plusieurs modes de réalisation et plusieurs variantes.
