実験手順

To the solution of 1-(2-fluoro-4-iodophenyl)-5,7-dimethyl-1H-imidazo[4,5-c]pyridine-2,6(3H,5H)-dione (23 mg, 0.0576) dissolved in dry DMF (2 mL) cooled to below 0° C. under an ice-bath, was added NaH (60% in mineral oil) (5.0 mg, 0.125 mmol). The cooling bath was removed after addition and the solution was allowed to stir at room temperature for 1 hour. The same solution was re-cooled to −5° C. in a dry-ice/acetone bath, and added cyclopropanesulfonyl chloride (28 mg, 0.20 mmol) dissolved in dry THF (0.5 mL) slowly. The mixture was allowed to warm to room temperature and stirred was and additional 16 hours. The reaction mixture was cooled to 0° C., additional NaH (60% in oil) (5.0 mg, 0.125 mmol), followed by cyclopropanesulfonyl chloride (15 mg, 0.11 mmol) were added. The solution was stirred at room temperature for additional 5 hours. To the same reaction mixture was added aqueous NaOH (1N) (5 mL). The mixture was heated to 65° C. for 40 minutes. After cooled to room temperature, aqueous HCl (1N) (25 mL) was added to acidify the solution, which was extracted with EtOAc (15 mL×3). The combined organic layers was washed with brine, dried (MgSO4), and concentrated under the reduced pressure to give a residue, which was HPLC purified. (9.6 mg, 35% yield).
