PROCEDURE
实验过程
In a 100 mL round-bottomed flask, HBTU (78 mg, 0.21 mmol), Hunig's base (0.14 ml, 0.79 mmol) and 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (70 mg, 0.16 mmol) were combined with DMF (3 ml) to give a light yellow solution. 1-Phenoxypropan-2-amine (48 mg, 0.32 mmol) was added and the reaction mixture was stirred at 25° C. for 16 h. The reaction mixture was diluted with EtOAc. The reaction mixture was poured into 50 mL sat NaHCO3 and extracted with EtOAc (2×50 mL). The organic layers were combined and washed with water (2×50 mL) then dried over MgSO4 and concentrated in vacuo to provide 81 mg (89%) of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (1-methyl-2-phenoxy-ethyl)-amide as a white solid. MS: (M+H)+=575.
