| abstract | ABSTRACT The present invention relates to a process for preparing terfenadine which is based on the reduction of terfena-done by an alkali metal borohydride, said process being characterized in that the reaction is carried out in a two-phase system in the presence of a phase transfer catalyst. The process of the present invention permits obtaining terfenadine in each of the two substantially pure polymorphic forms directly. |
