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), 1-(3-aminophenyl)ethanol (72.2 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 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, 40-70% ethyl acetate in hexanes) to give N-tert-butyl-2-(3-(1-hydroxyethyl)phenylamino)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (143 mg, 148 μmol, 42%) as a yellow solid. (EI/CI) m/z: 519.3 [M+H].
