Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 134997-74-3, name is 3-Oxo-3,4-dihydro-2H-benzo[b][1,4]oxazine-6-carbonitrile, This compound has unique chemical properties. The synthetic route is as follows., Computed Properties of C9H6N2O2
To an ice cooled solution of the title compound from Step A above (5.6 g), di-tert-butyl dicarbonate (14.06 g) and NiCl2-OH2O (1.53 g) in MeOH, NaBH4 (8.51 g) was added in portions. The mixture was vigorously stirred for Ih at O0C and Ih at room temperature. After the addition of diethylenetriamine (3.5 mL) the mixture was concentrated, diluted with EtOAc, washed subsequently with IN HCl, saturated aqueous NaHCO3 and saturated aqueous NaCl, dried (MgSO4), concentrated to afford the title compound as an off-white solid (7.91 g, 88%). [M+Na]+ = 397.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 134997-74-3.
