실험 절차

[2-(3-{2-dimethylcarbamoyl-4-[3-(2-methoxy-phenyl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-phenyl}-ureido)-ethyl]-methyl-carbamic acid tert-butyl ester (84 mg, 0.113 mmol) was dissolved in a solution of tetrahydrofuran (20 ml) and methanol (5 ml). A solution of aqueous potassium hydroxide (50% w/v, 5 ml) was added to the reaction mixture, and the combined mixture was allowed to stir for 1 hour at room temperature. The reaction mixture was quenched with sodium bicarbonate solution, and extracted with dichloromethane. The organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo. The crude product was purified by flash chromatography on silica gel (0-100% [10% methanol in ethyl acetate] in hexanes) to give 61 mg (92%) of [2-(3-{2-dimethylcarbamoyl-4-[3-(2-methoxy-phenyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-phenyl}-ureido)-ethyl]-methyl-carbamic acid tert-butyl ester. MS: m/z 587.5 (M+H+).
