4570-41-6, 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. Benzo[d]oxazol-2-amine, cas is 4570-41-6,the benzoxazole compound, it is a common compound, a new synthetic route is introduced below.
Step 1:To a solution of 4-fluorophenylacetic acid (1.0 g, 6.5 mmol) and 2-amino-benzoxazole (850 mg, 6.5 mmol) in CH2Cl2 (50 mL) was added DMAP (237 mg, 1.9 mmol) and EDC.HCl (1.5 g, 7.8 mmol).The reaction mixture was stirred at room temperature over night.The reaction mixture was concentrated in vacuo.Purification by chromatography (silica, 30percent ethyl acetate/CH2Cl2) afforded N-benzooxazol-2-yl-2-(4-fluorophenyl)acetamide (1.44 g, 82percent): 1H NMR (300 MHz, DMSO-d6) delta ppm 3.85 (s, 2H) 7.11-7.21 (m, 2H) 7.23-7.44 (m, 4H) 7.52-7.69 (m, 2H).
The chemical industry reduces the impact on the environment during synthesis,4570-41-6,Benzo[d]oxazol-2-amine,I believe this compound will play a more active role in future production and life.
