実験手順

4-[7-(2,2-Dimethyl-propionyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl]-benzoic acid was prepared starting from 1-(2-bromo-5H-pyrrolo[2,3-b]pyrazin-7-yl)-2,2-dimethyl-propan-1-one and 4-carboxyphenylboronic acid following general procedures as described in these Examples. Silica gel chromatography using 50-100% [5% AcOH:EtOAc]/Hexanes as eluant gave 10 mg (6%) of a pale brown solid. M+H=324.
