Procedure

To the solution of (S)-Methyl 5-[N-({5-[(3-{[(1,3-dimethyl-1H-pyrazol-5-yl)carbonyl]amino}phenyl)ethynyl]pyridin-3-yl}carbonyl)-S-phenylsulfonimidoyl]pentanoate (120 mg, 0.2 mmol) in THF (4 mL) at 0° C. was added dropwise a solution of aqueous NaOH (0.5 N, 2.0 mL). After the reaction mixture was stirred at 0° C. for 2 hours, 2 N HCl was carefully added to adjust the pH ˜5 followed by a partition between aqueous NH4Cl and EtOAc. The EtOAc layer was further washed with brine once and dried with anhydrous sodium sulfate. The organic layer was decanted, concentrated and subject to a gradient column chromatography (from EtOAc to MeOH-EtOAc 1:5) yielding the title compound as white foam in amount of (85 mg, 73%).
