Abstract
It is shown that 1-hydroxytriazolo[4,5-b]pyridine exists in alcohol solution primarily in the N-oxide form, whereas 3-hydroxytriazolo[4,5-b]pyridine exists in the hydroxy form. 4-Methyl-triazolo[4,5-b]pyridine 1-oxide is formed in the methylation of 1-hydroxytriazolo[4,5-b]pyridine, whereas 3-methoxytriazolo[4,5-b]pyridine is formed in the methylation of 3-hydroxytriazolo[4,-5-b]pyridine.
