반응 단계
To a solution of 1.0 g (7.0 mmol) of 2-chloro-6-methoxypyridine in 20 ml of dry THF cooled to -78° C. was added 10.9 ml (1.6M in hexanes, 17.4 mmol) n-BuLi under an atmosphere of nitrogen. The temperature of the mixture was allowed to raise to -40° C. before an addition of 4 ml ethylene oxide in 6 ml ether. The mixture was warmed to room temperature, 50 ml water was added and the aqueous layer was separated and extracted with 2×100 ml EtOAc. The organic extracts were combined, washed once with water, dried with Na2SO4, and concentrated in vacuo. The crude material was purified by dry column flash chromatography (hexane/EtOAc) to afford 0.22 g of 3-(2-hydroxyethyl)-6-chloro-2-methoxypyridine as a yellowish oil.
