Application of 369-26-6, 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. 369-26-6, name is Methyl 3-amino-4-fluorobenzoate, This compound has unique chemical properties. The synthetic route is as follows.
A mixture solution of 3-amino-4-fluoro-benzoic acid methyl ester (26 g, 153.8 mmol), 3-bromo-benzaldehyde (28.5 g, 153.8 mmol) and p-toluenesulfonic acid (590 mg, 3.2 mmol) in toluene (200 mL) was heated to reflux for 12 hours. Then the reaction mixture was cooled to room temperature. The solvent was removed in vacuo and the residue was washed with ether to afford 3-[(3-bromo-benzylidene)-amino]-4-fluoro-benzoic acid methyl ester (51.7 g, quant.) as a pale-white solid: MS calcd. for C15H11BrFlNO2 337.16, obsd. (ESI+) [(M+H)+] 336.0 338.0
The chemical industry reduces the impact on the environment during synthesis Methyl 3-amino-4-fluorobenzoate. I believe this compound will play a more active role in future production and life.
