Route 1: via N-Fluorobenzenesulfonamide

This is one of the most common routes for the synthesis of 5-Fluoro-2-iodobenzoic acid.
The reaction involves the reaction of N-fluorobenzenesulfonamide with benzoic acid, followed by reaction with sodium hydroxide to form the N-sulfonylsuccinamic acid.
The product is then treated with hydrogen iodide and sodium hydroxide to form the desired 5-Fluoro-2-iodobenzoic acid.

Route 2: via N-Fluorobenzenesuccinic acid

This route involves the reaction of N-fluorobenzenesulfonamide with benzene sulfonamide, followed by treatment with carbon tetrachloride and pyridine to form N-fluorobenzenesuccinic acid.
The product is then treated with hydrogen iodide and sodium hydroxide to form 5-Fluoro-2-iodobenzoic acid.

Route 3: via N-Fluorobenzenesulfonyl chloride

This is another commonly used synthetic route for 5-Fluoro-2-iodobenzoic acid.
The reaction involves the chlorination of N-fluorobenzenesulfonamide with chlorine, followed by treatment with benzoic acid and sodium hydroxide to form N-fluorobenzenesulfonyl chloride.
The product is then treated with potassium iodide and sodium hydroxide to form the desired 5-Fluoro-2-iodobenzoic acid.

Route 4: via N-Fluorophenyl N-(2,5-diiodo- benzoyl) sulfonamide

This route involves the synthesis of N-fluorophenyl N-(2,5-diiodo-benzoyl) sulfonamide, followed by treatment with hydrogen iodide and sodium hydroxide to form 5-Fluoro-2-iodobenzoic acid.
The synthesis of N-fluorophenyl N-(2,5-diiodo-benzoyl) sulfonamide involves the reaction of N-fluorophenyl sulfonamide with 2,5-diiodo-benzoic acid.

All the above routes are known to produce 5-Fluoro-2-iodobenzoic acid with high yield and purity.
