151230-42-1, 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-Bromo-2-methylbenzo[d]oxazole, cas is 151230-42-1,the benzoxazole compound, it is a common compound, a new synthetic route is introduced below.
[001255] Part 2: A mixture of 6-bromo-2-methylbenzo[d]oxazole (1.06 g, 5.0 mmol), 4,4,4?,4?,5 ,5 ,5?,5?-octamethyl-2,2?-bi( 1,3 ,2-dioxaborolane) (1.40 g, 5.5 mmol), KOAc (1.47 g, 15 mmol) and Pd(dppf)C12.CH2C12 (122 mg, 0.15 mmol) in dioxane ( 8 mL) was degassed and heated under N2 at 85 C. After 15 hours, the mixture was diluted with EtOAc, filtered through celite and concentrated. The residue was chromatographed to give 2-methyl-6-(4,4,5,5- tetramethyl- 1,3 ,2-dioxaborolan-2-yl)benzo [d]oxazole as a light orange solid (1 .30 g, 100%), MS m/z 260.4 [M+H].
The chemical industry reduces the impact on the environment during synthesis,151230-42-1,6-Bromo-2-methylbenzo[d]oxazole,I believe this compound will play a more active role in future production and life.
