2-Cyano-2-{6-[3-(2-methoxy-phenyl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-pyrimidin-4-yl}-N,N-dimethyl-acetamide (500 mg, 0.88 mmole) was suspended in tetrahydrofuran (11 mL) and cooled to 0° C. in an ice bath. Peroxy acetic acid (32% in acetic acid, 174 mg, 2.29 mmole) was added and after 10 min, the heterogeneous solution was removed from the ice bath and maintained at ambient temperature for 6 h. Sodium bisulfite (918 mg, 8.83 mmole) in water (10 mL) was added, followed by saturated aqueous sodium bicarbonate (20 mL) and the mixture extracted with ethyl acetate (3×30 mL). The combined organic portions were dried over magnesium sulfate, filtered, and concentrated to dryness. Silica gel chromatography of the crude residue afforded 2-{6-[3-(2-methoxy-phenyl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-pyrimidin-4-yl}-N,N-dimethyl-2-oxo-acetamide (315 mg, 89% yield) as a clear residue. MS: m/z 402.2 (M+H+).
