  • Patent number: 8884026
    Abstract: The present invention refers to an improved method for the preparation of compound 1-(2,6-difluorobenzyl)-1H-1,2,3-triazole-4-carboxylic acid substantially free of its 3H-I isomer. The invention also refers to the use of said intermediate for the preparation of Rufinamide and for obtaining a new polymorphic form of Rufinamide, designed as Form R-5. The invention also refers to said new polymorph of Rufinamide, and to the composition containing it and its use as medicament. The new polymorph of Rufinamide shows good stability and appropriate physico-chemical properties for its manipulation on industrial scale. Polymorph Form R-5 will be suitable to use as pharmaceutical for the treatment of convulsions, especially for the treatment of epilepsy.
