Zusammenfassung:A process for the preparation of Flecainide acetate, its salts, in particular its pharmaceutically acceptable salts, and intermediates thereof is described wherein 2,5-dibromotoluene is used as a starting material. The method involves a technique for preparing the starting material 2,5- bis (2,2,2-trifluroethoxy)toluene in high yields by reacting 2,5-dibromotoluene with 2,2,2-trifluoroethanol in the presence of a base and a copper-containing catalyst.
