2-Fluoro-4-nitrotoluene → 2-Fluoro-4-nitrobenzoic acid

Participants

Reaction Steps

This was prepared as described above in Example 33 except that benzyl 2-fluoro-4-hydroxybenzoate (prepared from 2-fluoro-4-nitrotoluene by oxidation with KMnO4 to give 2-fluoro-4-nitrobenzoic acid, followed by catalytic reduction to give 4-amino-2-fluorobenzoic acid, followed by diazotization/hydrolysis to give 4-hydroxy-2-fluorobenzoic acid which was converted to benzyl 2-fluoro-4-hydroxybenzoate in a fashion analogous to that described in Example 23) was used as starting material in place of benzyl 2-chloro-4-hydroxybenzoate.
