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 (150 mg, 351 μmol), 6-(methylsulfonyl)pyridin-3-amine (90.7 mg, 526 μmol), xantphos (60.9 mg, 105 μmol), Pd2(dba)3 (32.1 mg, 35.1 μmol) and cesium carbonate (229 mg, 702 μmol) in dioxane (2.4 mL) was heated in a microwave at 150° C. for 20 min. The mixture was cooled then filtered through a pad of celite. The filtrate was concentrated in vacuo then purified by chromatography (silica, 20-95% ethyl acetate in hexanes) to give N-tert-butyl-2-(6-(methylsulfonyl)pyridin-3-ylamino)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (97 mg, 187 μmol, 53%) as a yellow solid. (EI/CI) m/z: 458.3 [M+H].
