AbstractThe direct transformation of various secondaryamides into N-aryliminoethers via mild electrophilic activation with trifluoromethanesulfonic anhydride in the presence of 2-chloropyridine is described. Low temperature amide activation followed by warming to 0 °C and subsequent treatment with phenols provides the desired products with short overall reaction times and moderate to high reaction
