introduction | methyl 2-methoxy-4-aminobenzoate has a melting point of 155 to 159 degrees, a boiling point of 339.2±22.0 degrees (at one atmosphere), a density of 1.2, and a white or off-white solid at normal temperature and pressure. Methyl 2-methoxy-4-aminobenzoate is a commercial organic synthon. It has general solubility in chloroform and dichloromethane. It will be better when heated, but its solubility in water is poor. It can be used as an intermediate in organic synthesis. |
Use | Methyl 2-methoxy-4-aminobenzoate is a common organic synthesis intermediate. The ester group in the structure can be easily converted into a variety of active functional groups, including hydroxyl and aldehyde groups. In addition, the ester group can also obtain the corresponding amide compound through the urethane exchange reaction. The amino group can be diazotized to obtain the corresponding diazonium salt and then converted into various active functional groups. In addition, because amino and methoxy groups are both strong electron donating groups, the electron cloud density on the benzene ring is very high, and a series of nucleophilic substitution reactions can occur. For example, halogen atoms can be introduced at the 5th position of the benzene ring, including chlorine, Bromine, iodine. |
Synthesis method | For the synthesis of methyl 2-methoxy-4-aminobenzoate, the conventional synthesis method is from 2-methoxy-4-nitrobenzoate Starting from methyl ester, the target product is obtained by reducing the nitro group to the amino group through the reduction reaction. The commonly used reduction condition is palladium-carbon hydrogenation. Generally speaking, the hydrogen pressure used under this reaction condition often exceeds an atmospheric pressure. |
