The N-acylating and N-alkoxycarbonylation ability of the N-substituted 1,2,3-triazolo[4,5-c]pyridines 1a-e have been investigated. The alkoxycarbonyl triazolopyridine derivatives (1c-e) were readily prepared in 81-96 % yield (the corresponding tetrafluoroborate > 95 %). Triazolo[4,5-c]pyridine (1) h
