Abstract: This paper reports a novel synthesis of gefitinib starting from methyl3-hydroxy-4-methoxybenzoate. The process starts with alkylation of the starting material, followed by nitration, reduction, cyclization, chlorination and two successive amination reactions. The intermediates andtarget molecule were characterized by 1H-NMR, 13C-NMR, MSand the purities of all these compounds were determined by HPLC. This novelsynthetic route produced overall yields as high as 37.4%.
