Under reflux in ethanolic potassium hydroxide, IIIa readily lost a component of IIa and was converted to 5-methyl-6-N-phenylcarbamoylmethyl-3-pyridinol (IVa) in 95% yield. 2-Phenylpyricline N-oxides (V-VII) reacted with phenyl isocyanates (II) to afford 1:1 cycloadducts (IX-XI and XII-XIV). The reaction of 2-(p-nitrophenyl)pyridine N-oxide (VIII) with hIa directly afforded 2-anilino-6-(p-nitrophenyl)pyridine derivatives (XIVa and XVa).}, pages = {26--31}, title = {Reaction of Aromatic N-Oxides with Dipolarophiles : V. 1,3-Cycloaddition of 2-Substituted Pyridine N-Oxides with Phenyl Isocyanates}, volume = {1}, year = {1982} }
