The Synthetic Routes of 8-[(2-hydroxybenzoyl)amino]octanoic acid

8-[(2-hydroxybenzoyl)amino]octanoic acid, also known as salicylamide octanoic acid or simply SAL-802, is a synthetic compound commonly used in the chemical industry as a versatile intermediate for the production of various chemicals, drugs, and agricultural products.

The synthesis of SAL-802 involves several chemical reactions that are typically carried out in a multi-step process in a chemical plant.

The first step in the synthesis of SAL-802 involves the reaction of 4-nitrophenyl acetate with sodium hydride in the presence of a solvent such as DMF or DME.
The reaction results in the formation of 4-nitrophenyl-N-methyl-2-oxo-1,3-oxazolidin-3-ylcarbamate, which is then hydrolyzed using a base such as sodium hydroxide to yield 4-nitrophenyl-2-oxo-1,3-oxazolidin-3-carboxylate.

The next step in the synthesis of SAL-802 involves the reaction of 4-nitrophenyl-2-oxo-1,3-oxazolidin-3-carboxylate with 2-hydroxybenzaldehyde in the presence of a condensing agent such as dicyclohexylcarbodiimide (DCC) and hydroxycoumarin in a solvent such as dichloromethane or DMF.
The reaction results in the formation of 4-nitrophenyl-2-oxo-1,3-oxazolidin-3-carboxylic acid, which is then converted to 4-nitrophenyl-2-oxo-1,3-oxazolidin-3-amide using a condensation agent such as hydroxylamine or ammonia.

The next step in the synthesis of SAL-802 involves the reaction of 4-nitrophenyl-2-oxo-1,3-oxazolidin-3-amide with octanoic acid in the presence of a coupling agent such as dicyclohexylcarbodiimide (DCC) and hydroxyproline in a solvent such as dichloromethane or DMF.
The reaction results in the formation of 8-[(2-hydroxybenzoyl)amino]octanoic acid, which is then hydrolyzed using a base such as sodium hydroxide to yield the final product, SAL-802.
