Water → 2-Iodo-3-methoxypyridine

Participants

Reaction Steps

To a solution of 2-iodopyridin-3-ol (45.3 mg, 0.205 mmol) in DMF (3 mL) was added Cs2CO3 (334 mg, 1.030 mmol) and MeI (25 μL, 0.410 mmol). After 1 hour, the reaction was poured into water (10 mL), diluted with EtOAc (20 mL), washed with water (3×10 mL) and brine (10 mL). The organic layer was dried over Na2SO4, filtered, and concentrated to afford 2-iodo-3-methoxypyridine.
