Reaction Steps

3,6-diaminophthalic acid (0.21 g, 1.07 mmol) was dissolved in acetic anhydride (10 mL) at about 100° C., and stirred at this temperature for about 0.5 hour. After the reaction was cooled the product was filtered and washed with ether. A yellow precipitate was obtained (0.243 g, 86%). 1H NMR (300 MHz, DMSO) δ 9.85 (s, 2.0H, CONHAr), 8.29 (s, 2.1H, ArH), 2.17 (br s, 6.2H, COCH3).
