The benzoxazole compound, cas is 59-49-4 name is 2-Benzoxazolinone, mainly used in chemical industry, its synthesis route is as follows.,59-49-4
Example 251A 6-bromo-1,3-benzoxazol-2(3H)-one A mixture of 2-benzoxazolinone (3.00 g, 22.2 mmol), 1,3-dibromo-5,5-dimethylhydantoin (3.49 g, 12.2 mmol), and trifluoromethanesulfonic acid (5.00 g, 33.3 mmol) in dichloromethane (100 mL) at room temperature was protected from light, stirred for 1 hour, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 50% ethyl acetate/hexanes to provide the desired product.
As the rapid development of chemical substances, we look forward to future research findings about 59-49-4
