反応手順
1-[2-(3-Isopropoxy-phenyl)-5H-pyrrolo[2,3-b]pyrazin-7-yl]-2,2-dimethyl-propan-1-one was prepared starting from 1-(2-bromo-5H-pyrrolo[2,3-b]pyrazin-7-yl)-2,2-dimethyl-propan-1-one and 3-Isopropoxybenzeneboronic acid following general procedures as described in these Examples. Silica gel chromatography using 30-70% EtOAc in hexanes as eluant provided 140 mg (82%) of a yellow solid. MP 149-150° C., M+H=338
