| Product | Ethyl 2-(pyridin-3-yloxy)acetate | HCID 4763754 | 70% |
Reaction Steps
To a solution of 3-hydroxypyridine sodium salt, 6.4 g (36.0 mmol) in 200 mL of DMF was added 3.3 mL (30.0 mmol) of bromoethylacetate. The reaction mixture stirred overnight at rt. and was concentrated to dryness. The residue was partitioned between 20% isopropanol/chloroform and saturated aqueous NaHCO3. The mixture was washed with saturated NaHCO3, washed with brine, dried over Na2SO4, filtered and concentrated to dryness. The residue was purified by column chromatography using MeOH/chloroform as eluent and concentrated to dryness to give 3.8 g (70%) of the desired product as a tan oil. MS (ion spray) 182.1 (M+).
