The benzoxazole compound, name is 2-Benzoxazolinone,cas is 59-49-4, mainly used in chemical industry, its synthesis route is as follows.,59-49-4
Step 1: To a solution of benzoxazolinone (20 g, 0.148 mol) in 220 mL glacial acetic acid was added N-bromosuccinimide (NBS, 26.36 g, 0.148 mol), and the reaction mixture was stirred at room temperature for 63 hours before pouring into 1500 mL water. The precipitated product was washed thoroughly with water upon collection and recrystallized from EtOH to give 6-bromo-3H-benzoxazol-2-one (9) (25.09 g, 79%): Theory: C, 39.28; H, 1.88; N, 6.54; Br, 37.33. Found: C, 39.36; H, 2.02; N, 6.36; Br, 37.43. MP 192-194 C.
As the rapid development of chemical substances, we look forward to future research findings about 59-49-4
