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 mol), 6-methylpyridin-3-amine (56.9 mg, 526 mol), BINAP (10.9 mg, 17.5 mol), palladium (II) acetate (19.7 mg, 87.7 mol) and sodium tert-butoxide (84.3 mg, 877 mol) in DMF (1 mL) and toluene (500 μL) was heated in a microwave at 140° C. for 20 min. The reaction mixture was cooled then diluted with water and extracted into ethyl acetate (3×). The combined organic extracts were washed with brine then dried over magnesium sulfate. Purification by chromatography (silica, 30-70% ethyl acetate in hexanes) gave N-tert-butyl-2-(6-methylpyridin-3-ylamino)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (57 mg, 125 mol, 36%) as a brown solid. MS (EI/CI) m/z: 455.2 [M+H].
