2-[2-[2-(2-氯乙氧基)乙氧基]乙氧基]氧烷

反应条件: temp:140.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of methyl 5-t-octylsalicylate (37.7 g, 0.143 mole), 2-(2-[2-(2-chloroethoxy)ethoxy]ethoxy)tetrahydropyran (54 g, 0.214 mole), potassium carbonate (28 g, 0.217 mole) and N,N-dimethylformamide (250 ml) was heated at 140° C., under nitrogen, for 18 hours, with stirring. The mixture was cooled, diluted with ether, and then washed liberally with saturated sodium chloride solution. The ethereal solution was dried (MgSO4) and evaporated in vacuo to give an oil, which was chromatographed on silica gel to give 46 g of methyl 2-(2-[2-(2-[2-tetrahydropyranyloxy]ethoxy)ethoxy]ethoxy)-5-t-octylsalicylate. The mixture was cooled washed liberally with saturated sodium chloride solution The ethereal solution was dried (MgSO4) evaporated in vacuo to give an oil, which was chromatographed on silica gel
