実験手順
4,6-dichloro-2-[(trans)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl]-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine (racemic, 460 mg, 1.08 mmol), (2-(benzyloxy)-5-chloropyridin-3-yl)boronic acid (purchased from Combi-Blocks Inc.; 372 mg, 1.41 mmol) and 2M aqueous Na2CO3 (5 mL, 10 mmol) were added to degassed 1,2-dimethoxyethane (15 mL), followed by the addition of [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) (159 mg, 0.2 mmol). The reaction was heated at 90° C. for 6 hours. Water and EtOAc were added. The aqueous layer was extracted several times with EtOAc. The combined organic layers were dried over anhydrous Na2SO4, filtered, and concentrated in vacuo. The residue was purified on a silica gel column (0 to 30% EtOAc/hexanes) to afford 4-[2-(benzyloxy)-5-chloropyridin-3-yl]-6-chloro-2-[(trans)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl]-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine (racemic). MS ES calc'd. for C33H37Cl2N5O2 [M+H]+ 606. found 606.
