Procedure

To a solution of (R)—N-{dicyclopropyl[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]methyl}-2-methylpropane-2-sulfinamide (125 mg, 0.227 mmol) in methanol (2 mL) was added hydrochloric acid (4 M in 1,4-dioxane, 0.227 mL, 0.910 mmol). After 45 minutes, the reaction mixture was partitioned between ethyl acetate (20 mL) and saturated aqueous sodium bicarbonate solution (20 mL). The layers were separated and the organic layer was washed with brine, dried over sodium sulfate, filtered, and concentrated to afford N-(3-{2-[amino(dicyclopropyl)methyl]-1,3-thiazol-5-yl}-5-methylphenyl)-4-(trifluoromethyl)pyrimidin-2-amine (100 mg, 0.224 mmol, 99% yield) which was used without purification. MS ESI: [M+H]+ m/z 429.0.
