Introduction of a new synthetic route about Benzo[d]oxazol-2-amine

With the rapid development of chemical substances, we look forward to future research findings about 4570-41-6

Benzo[d]oxazol-2-amine, cas is 4570-41-6, it is a common heterocyclic compound, the benzoxazole compound, its synthesis route is as follows.,4570-41-6

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).

With the rapid development of chemical substances, we look forward to future research findings about 4570-41-6
