Reaktionsschritte

N-(10,11-Dihydroxyundecyl)phthalimide (2.35 g, 7.10 mmol) was stirred for 3 hours with HBr (6.90 mL of a 30% solution in acetic acid, 21.3 mmol). The mixture was then added over 10 minutes to a solution of water (50 mL), ice (25 g) and NaHCO3 (15 g) and stirred for an additional 30 min. The resulting reaction product was extracted with dichloromethane (3×70 mL) and the combined organic phase was dried using magnesium sulfate and evaporated, yielding a residue of N-(10-acetoxy-11-bromoundecyl)phthalimide.
