Name is 6-Bromobenzo[d]oxazol-2(3H)-one, as a common heterocyclic compound, it belongs to benzoxazole compound, and cas is 19932-85-5, its synthesis route is as follows.
To a solution of 6-bromo-1,3-benzoxazol-2(3H)-one (250 mg, 1.17 mmol) in anhydrous DMF (2 mL) at 0 C was added NaH (60% dispersion in mineral oil, 51.4 mg, 1.29 mmol) under nitrogen. The reaction mixture was stirred for 20 min. Then the reaction mixture was treated with (2-(chloromethoxy)ethyl)trimethylsilane (0.269 mL, 1.52 mmol) drop wise at 0 C and the resulting mixture was stirred for 1 h. The reaction mixture was warmed to 23 C, diluted with water (5 mL) and extracted with EtOAc. The combined organics were dried (Na2SO4), filtered, concentrated under reduced pressure. Purification (FCC, SiO2, 0 to 30% EtOAc/Hexane) afforded the title compound (383 mg, 95.3%).
19932-85-5, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,19932-85-5 ,6-Bromobenzo[d]oxazol-2(3H)-one, other downstream synthetic routes, hurry up and to see
