Abstract Oxidation of nitrogen-based methyl heteroaryls with molecular oxygen resulted in the formation of the corresponding benzyl alcohols. While experimentally easy and amenable to large-scale preparations, this approach has limitations with respect to the particular nature of heterocyclic substrates. Using this methodology, the title compound, 2-[N- (tert-butoxycarbonyl) amino]-4-pyridinecarbaldehyde, considered to be a versatile ...
