Name is 5-Nitro-2,3-dihydro-1,3-benzoxazol-2-one, as a common heterocyclic compound, it belongs to benzoxazole compound, and cas is 3889-13-2, its synthesis route is as follows.
Synthesis of 5-aminobenzo[d]oxazol-2(3H)-one (39-2) (0488) The mixture of 39-1 (5.1 g, 28.31 mmol), Pd/C (0.5 g) and HCO2NH4 (8.9 g, 141.57 mmol) in MeOH (200 mL) was stirred at room temperature overnight. Filtered with kiselguhr, concentrated in vacuo, the residue was added 5% NaHCO3 solution, collected the solid and washed with water (50 mL), dried in vacuo to get compound 39-2 as a brown solid (4 g, yield 94%).
3889-13-2, 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.,3889-13-2 ,5-Nitro-2,3-dihydro-1,3-benzoxazol-2-one, other downstream synthetic routes, hurry up and to see
