It is a common heterocyclic compound, the benzoxazole compound, 2-Benzoxazolinone, cas is 59-49-4 its synthesis route is as follows.
3 -(3 -IodopropyPbenzo d] oxazol-2(3H)-one[0164]; To a solution of 2-benzoxazolinone (2.0 g, 14.8 mmol) and potassium carbonate (3.07 g, 22.2 mmol) in NN-dimethylformamide (20 mL), was added l-bromo-3-chloropropane (4.4 mL,44.4 mmol, d = 1.6). After stirring at 55C for 18 hours, the reaction mixture was diluted with ethyl acetate (100 mL), washed with dilute citric acid, water and brine. The organic phase was dried over MgS04 and concentrated to obtain 3-(3-chloropropyl)benzo[i ]oxazol-2(3H)-one (3.1 g, 99%>).
59-49-4, 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.,59-49-4 ,2-Benzoxazolinone, other downstream synthetic routes, hurry up and to see
