Versuchsvorschrift

370 mg of 3-[3-(tert-butyldimethylsilanyloxy)-3-(4-fluorophenyl)propyl]-1-(4-fluorophenyl)-4-(4-hydroxyphenyl)azetidin-2-one are dissolved in 3 ml of absolute acetonitrile. 300 mg of KF•alumina (1.15 mol/100 g) and 375 mg of (3-bromopentyl)-trimethylammonium bromide are then added. The reaction mixture is stirred at room temperature overnight and then filtered. The mother liquor is concentrated using a rotary evaporator and the residue is purified using a 5 g SiO2 cartridge (dichloromethane/methanol 4:1). The product is obtained as an oil.
