実験手順

6-(4-(3-Bromopropyl)-3-(trifluoromethyl)-phenyl)-1-methyl-1H-imidazo[4,5-c]pyridine-4-carbonitrile (50 mg) and 2-oxopiperazine (103 mg) in DMF (750 μl) were heated at 100° C. in a microwave for 25 minutes. Purification by basic phase preparative LCMS afforded 1-methyl-6-{4-[3-(3-oxo-piperazin-1-yl)-propyl]-3-trifluoromethyl-phenyl}-1H-imidazo[4,5-c]pyridine-4-carbonitrile (15 mg).
