Reaction Conditions

Reaction Steps

4-Nitrophthalic acid (2.0 g, 9.5 mmol) was dissolved in 30 ml of 2-ethylhexanol, and then 0.3 ml of sulfuric acid was added. The mixture was heated at 120° C. for 24 hours, and the solvent was evaporated under reduced pressure. Excess 2-ethyihexanol was removed from the oily residue by distillation. The oily residue was dissolved in diethyl ether and washed three times with water and once with 10%Na2CO3 solution. The ether solution was dried over anhydrous sodium sulfate. After evaporation of the solvent, the residue was purified by silica gel column chromatography (n-hexane: acetic acid =30:1) to give 2.3 g (65.5%) of bis(2-ethylhexyl) 4-nitrophthalate (compound 411.)
