実験手順
2-(6-Fluoro-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (1-pyridin-4-yl-ethyl)-amide (100 mg, 0.19 mmol) was combined with DMF (2 mL) at 0° C. to give a yellow solution. Sodium hydride (60% in mineral oil, 23 mg, 0.56 mmol) was added and the reaction was stirred at 0° C. for 10 min. 4-(2-Bromoethyl)morpholine hydrochloride (55 mg, 0.28 mmol) was added and the reaction was stirred at 0° C. for 30 min then warmed to room temperature. The reaction mixture was stirred for 2 h at room temperature then quenched with 5 mL of brine and 10 mL of water and extracted with ethyl acetate (2×30 mL). The combined organic layers were washed with water and brine then dried with MgSO4, filtered and concentrated in vacuo. The crude material was purified by silica gel chromatography (0-10% methanol in dichloromethane) to give 70 mg (58%) of 2-[6-fluoro-1-(2-morpholin-4-yl-ethyl)-1H-indazol-3-yl]-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (1-pyridin-4-yl-ethyl)-amide as a foaming solid. MS: (M+H)+=645.
