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, 422 mg, 1 mmol), 5-chloro-2-fluoro-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (340 mg, 2 mmol) and Cs2CO3 (980 mg, 3 mmol) were added to degassed dioxane:water (10 mL: 2 mL), followed by the addition of [1,1′-bis(di-tert-butylphosphino)ferrocene]PdCl2 (130 mg, 0.2 mmol). The reaction was heated at 90° C. for 24 hours. Water and EtOAc were added. The aqueous layer was extracted with EtOAc several times. 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 60% EtOAc/hexanes) to afford 6-chloro-4-(5-chloro-2-fluoropyridin-3-yl)-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 C26H30Cl2FN5O [M+H]+ 518. found 518.
