Stage #1: With 3-benzyl-1-(1-((2,6-diisopropylphenyl)imino)ethyl)-1H-imidazol-3-ium chloride; potassium <i>tert</i>-butylate In N,N-dimethyl-formamide at 80℃; for 18 h; Inert atmosphere
Stage #2: at 65℃; for 1 h; Inert atmosphere
In the reaction flask, Under argon, a catalyst (9.9 mg, 0.025 mmol, 5 molpercent), Potassium tert-butoxide (0.0672 g, 0.6 mmol), DMF (3.0 mL) Benzoxazole (50.7 μl, 0.5 mmol), carbon dioxide gas, The reaction was stirred at 80 ° C for 18 hours under normal pressure. Cooled to 65 ° C, Methyl iodide (93 μl, 1.5 mmol) was added and the reaction was stirred at 65 ° C for 1 hour. The reaction was quenched with deionized water and the reaction product was extracted with ethyl acetate. The yield was 95percent by gas chromatography, The column chromatography was carried out in a volume ratio of ethyl acetate / petroleum ether 1:10 mixed solvent as developing solvent) in a yield of 90percent.
