Tags: SN2 rection between 4-(tert-butyldimethylsilyl)hex-5-yn-1-yl 4-methylbenzenesulfonate and NaN3 in DMF at 80 C provided (6-azidohex-1-yn-3-yl)(tert-butyl)dimethylsilane intermediate, which underwent in situ intramolecular thermal Huisgen azide–alkyne cycloaddition reaction. This one-pot process gave 4-(tert-butyldimethylsilyl)-4,5,6,7-tetrahydro-[1,2,3]triazolo[1,5-a]pyridine in 78% yield., triazole; triazolopyridine; Huisgen thermal cycloaddition; azide; intramolecular cyclization
