实验过程

2-(6-Chloro-1H-indazol-3-yl)-N-isopropyl-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (80 mg, 165 μmol) was dissolved in DMF (1 mL) and cooled to 0° C. Sodium hydride (10.6 mg, 264 μmol) was added and the mixture was stirred for 30 min. 2-(Chloromethyl)-1-methyl-1H-imidazole (23.7 mg, 181 μmol) was added and the mixture warmed to room temperature. After 15 h the mixture was diluted with water and extracted with ethyl acetate. The organic extracts were washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by chromatography (silica, 24 g Analogix column, dichloromethane) to give 2-(6-chloro-1-((1-methyl-1H-imidazol-2-yl)methyl)-1H-indazol-3-yl)-N-isopropyl-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (106 mg) as a yellow solid. MS (M+H)+=579.
