PROCEDURE
实验过程
A mixture of 2-bromo-N-tert-butyl-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (125 mg, 292 μmol), N-methylpyridin-3-amine (47.4 mg, 439 μmol), xantphos (50.8 mg, 87.7 μmol), Pd2(dba)3 (26.8 mg, 29.2 μmol) and cesium carbonate (191 mg, 585 μmol) in dioxane (2 mL) was heated in a microwave at 150° C. for 20 min. The mixture was cooled and then filtered through a pad of celite. The filtrate was concentrated in vacuo then purified by chromatography (silica, ethyl acetate in hexanes) to give N-tert-butyl-2-(methyl(pyridin-3-yl)amino)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (38 mg, 83.6 μmol, 29%) as a yellow gum. (EI/CI) m/z: 455.4 [M+H].
