To a solution of 2-methyl-propane-2-sulfinic acid[(R)-1-(6-bromo-pyridin-3-yl)-ethyl]-amide (650 mg, 2.13 mmol) in MeOH (5 mL) was added 4.0M HCl in dioxane (5.32 mL, 21.30 mmol). The clear reaction mixture was stirred at room temperature for 2.5 h. The reaction mixture became cloudy during this time. Ether (20 mL) was added, and the mixture was stirred for 10 min and then filtered, washed with ether (20 mL) to afford (R)-1-(6-bromo-pyridin-3-yl)-ethylamine HCl salt (500 mg, 87%) as a white solid.
