Participants

Reaction Steps

The pyridine N-oxide (d) (3.8 g) in trifluoroacetic anhydride (120 ml) was refluxed under argon for 24 hours, the solvent evaporated and the residue partitioned between chloroform and aqueous NaHCO3 (50 ml each). The aqueous fraction was re-extracted with chloroform (3×50 ml) and the combined organic solution dried and evaporated to give the product (1.8 g).
