Versuchsvorschrift
At RT, a solution of 1 g of 3-(2-{2-[2-(4-bromo-but-2-enyloxy)-ethoxy]-ethoxy}-ethoxy)-propionic acid tert-butyl ester (commercially available), 6 ml of TFA and 3 ml of DCM is stirred during 3 hrs, and then concentrated to dryness under RP. The oily residue is diluted with toluene and concentrated to dryness under RP affording 853 mg of 3-(2-{2-[2-(4-bromo-but-2-enyloxy)-ethoxy]-ethoxy}-ethoxy)-propionic acid in the form of a brown oil.
