Electrophilic aromatic substitution with N-methoxy-N-acylnitrenium ions generated from N-chloro-N-methoxy amides: syntheses of nitrogen heterocyclic compounds bearing a N-methoxy amide group
Treatment of N-alkoxy-N-chloroarylacetamides with triethylamine in ethanol results in removal of a chlorine atom and introduction of an ethoxy group at the C-2 position of arylacetamides in moderate yields.
