실험 절차

This example illustrates a synthesis of N-(11,10-Oxidoundecyl)glutarimide (inventive compound no. 1611). Sodium hydride (95%) (168 mg, 7 mmol) was added to a solution of glutarimide (565.6 mg, 5 mmol) in dimethyl sulfoxide (15 mL). After 20 minutes of stirring, 1-bromundec-10-ene (1.165 g, 5 mmol) was added and stirred for 12 hours at room temperature. The reaction mixture was then poured into a separatory funnel containing 100 mL of water and extracted with dichlormethane (5×75 mL). The organic extracts were combined, washed with water (50 mL) and brine (50 mL), dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The crude product obtained was further purified by flash chromatography over silica gel using 20% ethyl acetate/hexane eluant to yield 0.777 g (58.6% yield) N-(10-Undecenyl)glutarimide (inventive compound no. 1610).
