The present invention relates to process for preparing triazole compounds used in the treatment of epilepsy. The process comprises of reacting compound of 2, 6 difluoroazide (II) with 2, 3 dihalo compound (III) to form compound of formula I, which on further treatment with an aminating agent gives Rufinamide (IV). 2, 6 difluoroazide (II) is reacted with 2, 3 dihalo compound (III) in the presence of a solvent. The reaction can be carried out in a single pot without isolation of intermediates.
The invention relates to a novel, industrially viable, cost effective process for the preparation of 1-(2,6-difluorobenzyl)-1H-1,2,3-triazole-4-carboxamide commonly known as Rufinamide and intermediates thereof.
