Sodium hydride (19 mg, 0.48 mmol, 60 wt %) was added to a solution of 4-iodo-1H-pyrazole (47 mg, 0.24 mmol) in THF (2 mL) at 0° C. After 30 minutes, 4-(bromomethyl)pyridin-2(1H)-one (30 mg, 0.16 mmol) was added. The mixture was stirred at 25° C. for 12 hours. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (EtOAc/MeOH) to afford 4-((4-iodo-1H-pyrazol-1-yl)methyl)pyridin-2(1H)-one. MS ESI calc'd. for C9H9IN3O [M+H]+ 302. found 302. 1H NMR (400 MHz, DMSO-d6) δ 11.54 (s, 1H), 8.05 (s, 1H), 7.61 (s, 1H), 7.32 (d, J=6.8 Hz, 1H), 5.93-5.90 (m, 2H), 5.19 (s, 2H).
