To a solution of (R)-2-methyl-propane-2-sulfinic acid [(R)-1-(4-trifluoromethyl-pyridin-2-yl)-ethyl]-amide (225 mg, 0.76 mmol) in MeOH (4 mL) was added 4.0 M hydrogen chloride in dioxane (0.48 mL, 1.9 mmol). The reaction mixture was stirred at room temperature for 30 min then concentrated and dried under high vacuum to afford 225 mg of (R)-1-(4-trifluoromethyl-pyridin-2-yl)-ethylamine dihydrochloride as a viscous colorless oil which was used without further purification.
