Preparation of Flupirtine: it is prepared by reaction of 2-amino-3-nitro-6-chloro pyridine with p-fluorobenzyl amine. Then restore the resulting product, which is acylated by ethyl chloride. Finally, react with maleate in isopropyl alcohol to obtain the product.

Uses of Flupirtine: it is used as short-term treatment for surgery, trauma, burns and pain caused by toothache. What's more, it can act on the central nervous system without inhibition of respiration or cough.
