Abstract
Cette invention concerne un procédé de préparation de chlorhydrate de gemcitabine, procédé consistant à débloquer beta -1-(2'-désoxy-2',2'-difluoro-3',5'-di-O-benzoyl-D-ribofuranosyl)-4-aminopyrimidine-2-one avec une quantité catalytique d'une alkylamine en présence de méthanol ou d'éthanol dans un environnement totalement exempt d'eau; à traiter la solution obtenue avec l'acide chlorhydrique et un antisolvant; et à récupérer le chlorhydrate de gemcitabine solide obtenu.
