64037-07-6 - Reference Information
| Use | 5-bromobenzene [D] oxazol-2-amine is a heterocyclic derivative and can be used as an intermediate in organic synthesis. |
| preparation | to 2-amino-4-bromophenol (3)(59.6g,0.317mol) at room temperature A stirred solution in methanol (40.3) was added solid cyanogen bromide (0.38g, 1.2 mol, Eq) in small portions, the resulting mixture was stirred at 35 °c for 6 hours. (Note: cyanogen bromide is highly toxic, reagents and reactions should be carefully disposed of in the fume hood). The reaction mixture was quenched by addition of saturated aqueous Na2CO3 solution and the pH was adjusted to 7-8. Then the mixture was concentrated in vacuo to remove methanol. The residue was dissolved in ethyl acetate (600 mL), washed with water (100mL x 2) and brine (100mL), dried over MgSO4, and filtered. The filtrate was concentrated in vacuo to give the desired product 5-bromobenzene [D] oxazol-2-amine (65.2g,96.5% yield) as a yellow solid. |
