Reaction Steps

To a stirred solution of tert-butyl 4-((dimethylamino)methyl)phenethylcarbamate (0.14 g, 0.50 mmol) in dioxane (1 mL) at ambient temperature was added a 4M solution of hydrogen chloride in dioxane (4 mL). The resulting solution was stirred at ambient temperature for 30 minutes, then concentrated to afford 2-(4-((dimethylamino)methyl)phenyl)ethanamine dihydrochloride as a white solid (0.12 g, 98% yield).
