실험 절차

Compound [III] is prepared by a multi-stage process, comprising the conversion of 1,4dibromobenzene or hydroquinone to 1,4-bis(2,2,2-trifluoroethoxy)benzene, which is acetylated to form 2,5-bis(2,2,2-trifluoroethoxy)acetophenone. The acetophenone is then oxidized to form the corresponding benzoic acid derivative, which is then converted to its acid chloride and reacted either with 2-(aminomethyl)piperidine to form the Flecainide product in one step or with 2-(aminomethyl)pyridine, followed by catalytic hydrogenation of the pyridine ring, to form Flecainide in two steps.
