    • General procedure for the radical alkylation of 2-MeNQ. To the boiling solution of 2-MeNQ (2 g, 11.6 mmol), the appropriate dicarboxylic acid ( n=1-4 or 6, 11.9 mmol) and silver nitrate (0.5 g, 3 mmol) in a mixture of acetonitrile/water (50:20 mL for n=1-4, and 60:10 mL for n=6 ) an aqueous solution of ammonium persulfate (4.6 g, 20.2 mmol, 20 mL) was added dropwise over 45 min. The reaction mixture was cooled to room temperature, and 100 mL of water was added. The mixture was extracted with methylene chloride, and the organic phase was washed with water. Then the organic phase was extracted with an aqueous solution of potassium carbonate (1.5 g in 100 mL). The separated aqueous phase was washed with methylene chloride (2×) and acidified with diluted (1:5) hydrochloric acid (aq.) to pH 4 at 5-10°C. The resulting precipitated product was filtered off, washed with water and recrystallized to yield yellow crystals.
