Procedure

1M solution of lithium hydroxide (382.5 μl, 0.38 mmol) was added to a solution of 2-((R)-1-(1-(2-hydroxyacetyl)piperidin-4-yl)ethylamino)-4-(1-tosyl-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidine-5-carbonitrile (80 mg, 0.128 mmol) in tetrahydrofuran (2 mL). The reaction mixture was stirred at room temperature for 1 hour. The crude mixture was concentrated to dryness and redissolved in ethyl acetate. The organic phase was washed with water, dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified on silica gel by flash column chromatography (ISCO Companion|) to afford the title compound as a white solid (30 mg, 50% yield).
