Synthesis
6.8 g (0.1 mol) of imidazole, 45.5 g (0.1 mol) of 1-bromohexadecane and 2.4 g (7.5 mmol) of tert-butylammonium bromide (TBAB) were added to a wide-necked conical flask. The reaction mixture was adsorbed on a solid carrier of potassium carbonate mixed with potassium hydroxide in the ratio of 1:1 and placed in an open vessel in a household microwave oven and irradiated intermittently for 3 min (20 s per irradiation) at 300 W power until the mixture turned into a paste. Upon completion of the reaction, the reaction mixture was diluted with dichloromethane, washed sequentially with water, the organic phase was separated and dried with anhydrous sodium sulfate. After filtration to remove the desiccant, the solvent was evaporated under reduced pressure to give the crude product.
