2-[2-[2-(2-hydroxyethoxy)ethoxy]ethoxy]ethyl methanesulfonate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 250 mL of dichloromethane was added to 25 g of tetraethylene glycol and 32.8 g of silver oxide, and then a solution of 17.7 g of methanesulfonyl chloride in 50 ml of dichloromethane was added dropwise. After stirring the reaction solution at room temperature for 2 days, the solution was filtered with a celite, and then the filtrate was concentrated under reduced pressure. The residue was purified with silica gel column chromatography to obtain 24 g of the objective compound. the solution was filtered with a celite the filtrate was concentrated under reduced pressure The residue was purified with silica gel column chromatography
