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 (100 mg, 0.179 mmole) in methanol (3.6 mL) was cooled to 0° C. in an ice bath. Potassium hydroxide (aqueous 50% w/v, 0.06 mL) was added, the solution removed from the ice bath, maintained at ambient temperature for 15 hrs, and quenched with acetic acid (0.06 mL). The resulting solution was concentrated to remove all volatile organics, dissolved in ethyl acetate (10 mL), washed with sodium bicarbonate (5 mL), then with water (5 mL), then with brine (5 mL), and dried over magnesium sulfate. The solution was filtered and concentrated to dryness to afford 2-{6-[3-(2-methoxy-phenyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-pyrimidin-4-yl}-N,N-dimethyl-2-oxo-acetamide (63 mg, 72%) as a yellow solid which was used without further purification. MS: m/z 402.2 (M+H+).
