Procedure

A solution of (S)—N—((S)-(3-methoxypyridin-2-yl)(4-(trifluoromethyl)-phenyl)methyl)-2-methylpropane-2-sulfinamide (0.576 g, 1.491 mmol) in MeOH (6 mL) was treated with hydrochloric acid, 4.0 M solution in 1,4-dioxane (0.75 mL, 3.00 mmol) and stirred at rt for 2 h. The reaction was concentrated on the rotary evaporator resulting in a gummy residue which was taken up in EtOAc (100 mL), saturated aqueous NaHCO3 (50 mL), and H2O (25 mL). The resulting mixture was transferred to a separatory funnel and after vigorous extraction, the organic layer was separated, dried over anhydrous sodium sulfate, and concentrated to yield the product (S)-(3-methoxypyridin-2-yl)(4-(trifluoromethyl)-phenyl)methanamine as a light-brown oil which was used without further purification in the next step.
