Study of the chemical mechanism for the aging of the fischer reagent
1H and13C NMR spectroscopy were used to show that alkylation of the nitrogen atom in pyridine by dimethyl sulfate proceeds with the formation of N-methylpyridinium methyl sulfate in the Fischer reagent upon use and during storage along with other reactions already described in the literature.
