Acetic acid (60.7 mg, 1.01 mmol), N,N-diisopropylethylamine (174 mg, 1.348 mmol) and HATU (513 mg, 1.348 mmol) were added to 4-(5-chloropyridin-3-yl)-3-[(trans-4-methylcyclohexyl)methyl]-2-[(4aR,7aR)-octahydro-1H-cyclopenta[b]pyrazin-1-yl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile (177 mg, 0.33 mmol) in DMSO (1.5 ml), and the mixture was stirred at room temperature overnight. The reaction was then diluted with EtOAc, washed with water and brine, dried over sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel, eluting with EtOAc/isohexane to give 2-[(4aR,7aR)-4-acetyloctahydro-1H-cyclopenta[b]pyrazin-1-yl]-4-(5-chloropyridin-3-yl)-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine-6-carbonitrile. MS ESI calc'd. for C29H34ClN7O [M+H]+ 532. found 532.
