Synthetic Route of 38469-84-0,Some common heterocyclic compound, 38469-84-0, name is 5-Methoxy-2-nitrobenzonitrile, molecular formula is C8H6N2O3, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
2-Amino-5-methoxybenzonitrile: [0441] A 100 mL round bottom flask was charged with 5-methoxy-2- nitrobenzonitrile (1.7 g, 9.55 mmol), sodium dithionite (4.99 g, 29 mmol), water (15 mL) and EtOH (50 mL). The resulting mixture was heated at reflux for 1 h. Work-up: the reaction mixture was concentrated in vacuo to remove ethanol then extracted with EtOAc (50 mL). The organic layer was dried over anhydrous Na2S04 and concentrated in vacuo, to afford 1.4 g (quantitative) of the product as yellow oil. It was used in the next step without further purification.
The synthetic route of 38469-84-0 has been constantly updated, and we look forward to future research findings.
