Versuchsvorschrift

2-{2-[2-(2-allyloxy-ethoxy)-ethoxy]-ethoxy}-ethanol (9) (3.6 g, 15 mmol), succinic anhydride (1.8 g, 18 mmol), pyridine (1.22 mL, 15 mmol), dimethylaminopyridine (183 mg, 10 mol %), and dry toluene (5 mL) were charged into a screw cap culture tube. The mixture was stirred at 80° C. for 10 hours. Next, the reaction was stopped by adding 10% HCl (6 mL) and the reaction mixture was extracted with CH2Cl2 (3×10 mL). An organic layer was collected and dried on MgSO4. AMBERLITE™ resin IR-120 (+) (2 g) was added and stirred to perform ion exchange. The resin was filtered off and the filtrate was concentrated to obtain yellow oil (5.2 g, 92%). The compound was used without further purification. The NMR analysis result of the compound is as follows.
