실험 절차

A solution of 7.77 g of 2,6-dimethoxyphenoxyethanol in 30 ml of pyridine was cooled and 4.7 g of thionylchloride was added with stirring. After 20 minutes, stirring, the reaction mixture was heated on the steam bath for 2 hours. After cooling, the reaction mixture was evaporated in reduced pressure. The residue was extracted with CHCl3, purified with silicagel chromatography (eluent: EtOAc) 1.82 g of objective compound was obtained.
