19932-85-5, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 6-Bromobenzo[d]oxazol-2(3H)-one, cas is 19932-85-5,the benzoxazole compound, it is a common compound, a new synthetic route is introduced below.
EXAMPLE 121 6-Bromo-3-trityl-3 H-benzooxazol-2-one 6-Bromo-3H-benzooxazol-2-one (0.165 g, 0.77 mmol) was added portionwise into a 0 C. suspension of NaH (44.8 mg, 1 mmol, 55%) in dry DMF (4 ml). After 1 hour stirring at room temperature, a solution of triphenylmethylchloride (0.24 g, 0.85 mmol) in DMF (0.5 ml) was added. The reaction mixture was stirred 1 hour at room temperature then quenched with H2O (15 ml). The aqueous phase was extracted with ethyl acetate, the combined organic phases were washed with H2O and brine, dried over Na2SO4 and concentrated to provide 6-bromo-3-trityl-3H-benzooxazol-2-one (0.27 g, 77%) as a beige solid, MS: Mm/e=457.1 (M+H+).
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 6-Bromobenzo[d]oxazol-2(3H)-one, 19932-85-5
