Reaction of N-(4-pyridylmethyl)benzamide N-oxides 2 with 1,3-diphenyl-1,3-propanedione in the presence of acetic anhydride afforded 1,1-dibenzoyl-2-(4-pyridyl)-2-(benzoylamino)ethanes 4 in low yield. Treatment of N-[(α-acetoxy)4-pyridylmethyl]benzamides 3 with 1,3-diphenyl-1,3-propanedione in the presence of triethylamine and chloroform as a solvent provided 4 in high yield. Reaction of 4 with nucleophiles
