Preparation Process Of Retigabine And Its Intermeadiates

Invention relates to an efficient, economical and industrially viable process for the preparation of 2-amino-4-(4-fluorobenzylamino)-1-ethoxycarbonylaminobenzene (Retigabine). The process replaces genotoxic and potentially hazardous hydrazine hydrate as a deprotecting agent by new set of deprotecting agents . This technology also relates to the preparation processes of Retigabine intermediates.
