5-BROMO-BENZOOXAZOLE-2-CARBOXYLIC ACID METHYL ESTER Use and Manufacturing

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), 5-bromobenzoxazole (99.01 mg, 0.5 mmol) was added to the carbon dioxide gas, and 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, 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 85percent.
