Reaction Steps

To a solution of tert-butyl 4-((2,2,2-trifluoroethylamino)methyl)piperidine-1-carboxylate (1.49 g, 5.03 mmol) in DCM (25 mL) was added 4 N HCl in dioxane (5.03 mL, 20.11 mmol). The reaction was stirred at RT. After 16 hours, the white precipitate was collected by vacuum filtration, washed with diethyl ether, and dried in vacuo, to generate 2,2,2-trifluoro-N-(piperidin-4-ylmethyl)ethanamine dihydrochloride as a white powder (1.07 g, 3.98 mmol, 79% yield).
