Reaction Steps

4-(4,6-Dimethoxy-1,3,5-triazine-2-yl)-4-methylmorpholinium chloride (177 mg) is added to a solution of 48 mg (0.29 mmol) of terephthalic acid and 128 mg (0.64 mmol) of 4-dimethylamino-6-aminoquinaldine in 6 mL of dimethylformamide, at a temperature in the region of 20° C. The mixture obtained is stirred at a temperature in the region of 20° C. for about 12 hours. The reaction mixture is successively taken up in 2 mL of acetonitrile and 2 mL of diisopropyl ether, and the precipitate thus obtained is slowly filtered on a 6 mL BOND-ELUT cartridge filled with sintered material. The insoluble matter obtained is washed with diisopropyl ether and then dried under argon. 154 mg of N,N′-bis(4-dimethylamino-2-methylquinolin-6-yl)-terephthalamide are thus obtained in the form of a beige powder of whose characteristics are the following:
