Reaction Steps
2,2-Dimethyl-1-[2-(3-piperidin-1-ylmethyl-phenyl)-5H-pyrrolo[2,3-b]pyrazin-7-yl]-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-(piperidin-1-ylmethyl)phenylboronic acid hydrochloride following general procedures as described in these Examples. Silica gel chromatography using 0-20% [5% NH4OH:MeOH]/DCM as eluant gave a brown solid which was washed with 1:2 Et2O/Hexanes to provide 70 mg (36%) of a pale brown solid. MP 176-177° C., M+H=377.
