Reaction Steps

Phthalimide (892 mg, 6.01 mmol) was dissolved in DMF (10 mL) followed by addition of 3-(chloromethyl)-1,2,4-oxadiazole (713 mg, 6.01 mmol), cesium carbonate (2.95 g, 9.02 mmol) and tetrabutylammonium iodide (3.35 g, 8.02 mmol), and then the mixture was stirred at room temperature for 2.5 hours. Water was added to the reaction mixture, and the resulting precipitate was collected by filtration and dried under reduced pressure to give N-(1,2,4-oxadiazol-3-ylmethyl)phthalimide (1.15 g; yield 83%).
