To a solution of 4-[5-chloro-2-(dimethylamino)pyridin-3-yl]-2-[(trans)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl]-N-hydroxy-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridine-6-carboximidamide (racemic, 22 mg, 0.075 mmol) and 1,1′-carbonyldiimidazole (12 mg, 0.07 mmol) in acetonitrile (1 mL) was added 1,8-diazabicycloundec-7-ene (23 mg, 0.15 mmol). The reaction was stirred at room temperature for 18 hours. The reaction was then diluted with CH2Cl2 and washed with water. The organic layer was dried over anhydrous Na2SO4 and concentrated. The residue was purified on a silica gel column (0 to 10% MeOH/CH2Cl2) to afford 3-{4-[5-chloro-2-(dimethylamino)pyridin-3-yl]-2-[(trans)-hexahydrocyclopenta[b][1,4]oxazin-4(4aH)-yl]-3-[(trans-4-methylcyclohexyl)methyl]-3H-imidazo[4,5-c]pyridin-6-yl}-1,2,4-oxadiazol-5(4H)-one (racemic).
