Yield | Reaction Conditions | Operation in experiment |
---|---|---|
82% | In the reaction flask, Under argon, a catalyst (9.9 mg, 0.025 mmol, 5 mol%), potassium tert-butoxide (0.0672 g, 0.6 mmol) DMF (3.0 mL), 6-methoxybenzothiazole (82.5 mg, 0.5 mmol), access to carbon dioxide gas, The reaction was stirred at 80 C for 18 hours under normal pressure. Cooled to 65 C, methyl iodide (93 mul, 1.5 mmol) was added, The reaction was stirred at 65 C for 1 hour. Cooled to room temperature, the reaction was terminated with deionized water, The reaction product was extracted with ethyl acetate and purified by column chromatography (Using a mixed solvent of ethyl acetate / petroleum ether in a volume ratio of 1:10 as a developing solvent) The yield was 82%. |
