6-Bromobenzo[d]oxazol-2(3H)-one, cas is 19932-85-5, it is a common heterocyclic compound, the benzoxazole compound, its synthesis route is as follows.,19932-85-5
A mixture of 6-bromo-1,3-benzoxazol-2(3H)-one (2 g; 9.34 mmol) and copper (I) cyanide (1.42 g; 15.86 mmol) in 6 ml DMF is heated at 150C under nitrogen atmosphere for 22 hr. After cooling to room temperature, a solution of 1.55 g (31.6 mmol) of sodium cyanide in 32 ml water is added followed by 1 hr stirring. The system is extracted thoroughly with ethyl acetate, washed with brine, dried and concentrated in vacuo to provide 1.5 g (93 % yield) of the title compound enough pure as to prosecute the syntesis.
19932-85-5 is used more and more widely, we look forward to future research findings about 6-Bromobenzo[d]oxazol-2(3H)-one
