Reaction Steps

1N NaOH (50 mL) was slowly added dropwise at room temperature over 30 min to a stirred solution of di-methyl nitroterephthalate (12 g, 0.05 mmol) in dioxane (100 mL). After stirring overnight at room temperature the reaction was diluted with water, washed with ether, acidified with 1N HCl (50 mL) and extracted with ethyl acetate. After drying the ethyl acetate phase (MgSO4) and evaporation, the resulting residue was purified by flash chromatography (silica gel, 98:2:0.1 CHCl3 :MeOH:HOAc) to yield the title compound (8.07 g, 72%).
