참여 물질

반응 단계

A 25 ml reaction flask, equipped with a reflux condenser, an oil bath and a magnetic stirrer was charged with 2 g (11.9 mmol) of 2-[2-(2-chloroethoxy)-ethoxy]-ethanol (Fluka), 4 g of sodium iodide and 3 g of sodium hydrogencarbonate in 20 ml of Acetone. The reaction mixture is refluxed over night and when cold, filtered. The filtrate is concentrated at the rotavap, dissolved in 5 ml of CH2Cl2 and filtered again. Then the filtrate is concentrated again at the rotavap to yield 2.5 g of a yellow oil. The NMR shows a pure substance (CDCl3) 2.58 s broad (1H/OH); 3.22 t (2H/CH2-J); 3.53-3.77 m (10H/CH2—O).
