A new route to<i>N</i><sup>2</sup>- and<i>N</i><sup>3</sup>-substituted-2,3-diaminopyridines. Synthesis of 1- and 3-alkoxycarbonyl-<i>v</i>-triazolo[4,5-<i>b</i>]pyridines
Selective protection of the 3-amino group of 2,3-diaminopyridine with benzyl chloroformate allows a new synthesis of 3-methylamino- and 3-amino-2-alkylaminopyridines. The preparation of 1- and 3-alkoxycarbonyl-v-triazolo[4,5-b]pyridines is also reported.
