Recommanded Product: 73792-08-2

1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride was added to a pyridine (500 ml) solution of 18.9 g of methyl 4-amino-2-fluorobenzoate and 16.5 g of picolinic acid, and stirred at room temperature for 2 hours. The solvent was evaporated away under reduced pressure, 600 ml of ethyl acetate was added to the residue, the organic layer was washed with aqueous 0.25 N hydrochloric acid solution, aqueous 0.25 N sodium hydroxide solution and saturated saline water, dried, concentrated under reduced pressure, solidified from a mixed solvent of hexane/ethyl acetate, and the solid was taken out through filtration. This was dried under reduced pressure to obtain 28.3 g of the entitled compound as a white solid.

The synthetic route of 73792-08-2 has been constantly updated, and we look forward to future research findings.
