Procedure

To a solution of (R)-2-(4-cyano-2-fluoro-5-(3-methylisothiazol-5-ylamino)phenylamino)-3-(pyridin-2-yl)propanamide (53 mg, 0.133 mmol) in EtOH (1 mL) and DMSO (0.5 mL), aq. 1N NaOH (0.5 mL, 0.50 mmol) and aq. H2O2 (50%, 0.5 mL) were added. The mixture was stirred at room temperature for 15 min. HOAc (0.5 mL) was added. The mixture was purified by HPLC to give the titled compound (16 mg). MS 415.1 (M+H); UV 214.4, 278.0, 302.6 nm.
