実験手順

To a 35 ml seal tube, 1-(2-bromo-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-yl)-2,2-dimethylpropane-1-one (0.25 g, 0.000606 mole) and (5-aminopyridin-2-yl)methanol (0.09 g, 0.00728 mole) was taken in toluene (3.0 ml). The reaction mixture was purged with argon for 15 min at RT and NaOtBu (0.11 g, 0.00121 mole) was added and the reaction mixture was further purged for 30 min with argon. BINAP (0.037 g, 0.000060 mole) and Pd2(dba)3 (0.027 g, 0.000030 mole) were added and the reaction mixture was heated to 110° C. for 3 hrs. After completion of the reaction, the reaction mixture was filtered through celite bed and washed with ethyl acetate. Filtrate was collected and concentrated to afford crude product which was purified using column purification by eluting with 40-50% ethyl acetate in hexanes to yield 0.1 g of 1-(2-(6-(hydroxymethyl)pyridin-3-ylamino)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazin-7-yl)-2,2-dimethylpropan-1-one.
