To tert-butyl 4-(2-(N-methyl-1H-1,2,3-triazole-4-carboxamido)ethyl)piperidine-1-carboxylate (step 2) (190 mg, 0.563 mmol) in EtOAc (5 ml) was added 4N HCl in dioxane (5 ml, 20.00 mmol). The mixture was stirred for 30 mins and concentrated under reduced pressure to give crude N-methyl-N-(2-(piperidin-4-yl)ethyl)-1H-1,2,3-triazole-4-carboxamide as a gum. This was used in the next step without further purification.
