Reaktionsschritte

This example illustrates a synthesis of N-(5,6-Oxidohexyl)phthalimide (inventive compound no. 1103). 1-bromo-5-hexene (6.52 g, 40 mmol) was added to a potassium phthalimide (7.4 g, 40 mmol) suspension in 50 mL of dimethyl sulfoxide and stirred overnight. After 12 hours of stirring at room temperature, the reaction was poured into a separatory funnel containing 300 mL of water and extracted with dichloromethane (5×200 mL). The organic extracts were combined, washed with water (100 mL) and brine (100 mL), dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The crude product obtained was further purified by flash chromatography over silica gel (eluant: 10% acetone/hexane) to yield 9.2 g (100% yield) of N-(5-Hexenyl)phthalimide (inventive compound no. 1101).
