Determination of the Structure of Products of the Reduction of Pyridostigmine with NaBH4

The chemical structure of 5 different products of pyridostigmine obtained by reduction with NaBH4 was determined by GC - MS and subsequently confirmed by means of 1H and 13C NMR spectroscopy.Reaction conditions leading almost exclusively to the main product: 3--1-methyl-1,2,5,6-tetrahydropyridine (4) have been determined. - Key words: Pyridostigmine, 3--1-methylpyridiniumbromide, Reduction Products, 1H NMR Spectra, 13C NMR Spectra
