This acid catalyst can be selected from sulfuric acid, p-toluenesulfonic acid and the like. During the reaction, it needs to be heated and refluxed to make the two fully react to form methyl 3-fluoro-4-nitrobenzoate. Subsequently, with a suitable reducing agent, such as iron powder, zinc powder and hydrochloric acid system, or hydrogen under the catalysis of palladium carbon, the nitro group is reduced to an amino group to obtain methyl-4-amino-3-fluorobenzoate.

Second, 3-fluorobenzoic acid is used as the starting material. First, a mixed acid (a mixture of nitric acid and sulfuric acid) is used for nitrification to obtain 3-fluoro-4-nitrobenzoic acid. This reaction needs to be controlled at temperature to prevent side reactions from occurring. Then, as described above, the first esterification is followed by the reduction of nitro groups, and the target product can also be obtained.

Third, 4-amino-3-fluorobenzaldehyde is used as raw material. First, the aldehyde group is oxidized to a carboxyl group with an oxidizing agent, such as potassium permanganate and potassium dichromate, to obtain 4-amino-3-fluorobenzoic acid. Then it is esterified with methanol under acid catalysis to synthesize methyl-4-amino-3-fluorobenzoate.

All synthesis methods have advantages and disadvantages. It is necessary to weigh and choose according to the availability of raw materials, cost, and difficulty of reaction conditions.
