実験手順

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 (80 mg, 0.139 mol) was dissolved in a 4:6 solution of TFA:DCM (6.5 mL). After stirring at room temperature overnight, the volatiles were removed under reduced pressure. The crude material was then dissolved in dichloromethane and treated with ethylenediamine (837 mg, 13.9 mmol). After stirring at room temperature overnight, water was added and the resulting precipitate was collected by filtration to provide 35 mg (57%) of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (1-methyl-2-phenoxy-ethyl)-amide as a yellow solid.
