Reaction Steps
From 1-fluoro-4-nitrobenzene by heating with glycine at reflux in a mixture of aqueous sodium bicarbonate and dioxane to give (4-nitro-phenylamino)-acetic acid, followed by treatment with formaldehyde and formic acid at reflux to give [methyl-(4-nitro-phenyl)-amino]-acetic acid. Treatment with thionyl chloride and catalytic DMF to give the acid chloride followed by amide formation with 2-amino-4,6-dimethylpyridine in triethylamine and chloroform gives N-(4,6-dimethyl-pyridin-2-yl)-2-(4-nitro-phenylamino)-acetamide. The amide is the reduced with borane-dimethylsulfide in THF at reflux then catalytic hydrogenation over Raney nickel in methanol gives the required aniline.
