Reaction of N-(4-Pyridylmethyl)benzamide N-oxides with Ethyl Cyanoacetate in the Presence of Acetic Anhydride
Reaction of N-(4-pyridylmethyl)benzamide N-oxides 2a-f with ethyl cyanoacetate in the presence of acetic anhydride yield dimerization compounds 3a-f and (E)-ethyl 2-cyano-3-(4-pyridyl)-3-(benzoylamino)acrylates 4a-f, which react with hydrazine to give 4-cyano-3-(4-pyridyl)-3-pyrazolin-5-one 9 and the corresponding benzamides 10a-f.
