As a common heterocyclic compound, it belong benzoxazole compound,6-Bromobenzo[d]oxazol-2(3H)-one,19932-85-5,Molecular formula: C7H4BrNO2,mainly used in chemical industry, its synthesis route is as follows.,19932-85-5
[Reference Example 20] (0470) (0471) To the solution of 100 mg of 6-bromobenzo[d]oxazol-2(3H)-one in 1.0 mL of tetrahydrofuran, 57.7 mg of potassium tert-butoxide was added under ice-cooling, and the resultant was stirred under ice-cooling for 10 minutes, followed by addition of 61.1 muL of benzyl bromide. The reaction mixture was stirred at room temperature for 20 minutes and at an external temperature of 50C for two hours, then cooled to room temperature and allowed to stand overnight. Water and ethyl acetate were added to the reaction mixture. The organic layer was separated and dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate) to give 133 mg of 3-benzyl-6-bromobenzo[d]oxazol-2(3H)-one as a white solid. 1H-NMR (CDCl3) delta: 4.99 (2H, s), 6.55-6.92 (1H, m), 6.98-7.98 (7H, m).
With the synthetic route has been constantly updated, we look forward to future research findings about 6-Bromobenzo[d]oxazol-2(3H)-one,belong benzoxazole compound
