Abstract:Phenylcarbamate was synthesized using O-nitrotoluene as the starting material through a series of reactions including nitro reduction, N-acylation and O-methylation reaction. Under the optimal conditions, the total yield was 76.3% based on o-nitrotoluene. And the structure of the prepared product was confirmed by 1H NMR and MS.The experimental results showed that the process exhibited mild reaction conditions, simple operation, high yield, and was suitable for industrial production. |
Key words:methyl N-methoxy-N-(2-methyl)phenylcarbamate; pyraclostrobin; O-nitrotoluene; synthesis process |
