177210-33-2, name is 5-Hydroxy-2H-benzo[b][1,4]oxazin-3(4H)-one, belongs to amides-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Computed Properties of C8H7NO3
[00327] A solution of 5-hydroxy-2H-benzo[b][l,4]oxazin-3(4H)-one (100 mg, 0.604 mmol) and K2C03 (167 mg, 1.21 mmol) in anhydrous DMF (5 mL) was stirred at 27 C for 5 minutes, then ethyl 2-bromoacetate (121 mg, 0.727 mmol) was added. The reaction mixture was stirred at 27 C for 16 h and concentrated. MS (ESf ) e/z: 238.0 [M+l]+.
The synthetic route of 177210-33-2 has been constantly updated, and we look forward to future research findings.
