2-Fluoro-5-nitrobenzoic acid (I) was converted to the corresponding acid chloride (II) by chlorination of with SOCl2. Condensation of acid chloride (II) with 3,4-dimethoxybenzylamine (III) provided amide (IV). The aromatic fluorine atom of (IV) was then displaced with (R)-2-amino-1-propanol (V) in hot pyridine to furnish the title anthranilic acid derivative.
