Identification and Synthesis of Flecainide Acetate Impurities and Its Control to ICH Limit

The improved synthesis of Flecainide acetate (I) is conferred in this article. chief intent to present article identify and the process related impurities acetate.
 also provides complete study characterization impurities. Most are in-situ generated intermediates which tend carryforward final step synthesis. more interesting part formation 2,5 –bis (2,2,2-trifluoroethoxy)-N-((4-methylpiperidine-2-yl) methyl) benzamide impurity during synthesis.
 confers its control acetate.
