Procedure

A solution of pyrimidine-5-carboxylic acid (0.088 g, 0.709 mmol), N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride (0.136 g, 0.709 mmol) and 1H-1,2,3-benzotriazol-1-ol (0.072 g, 0.534 mmol) in DMF (4 mL) was heated at 40° C. for 15 minutes. Finally, 3″-fluoro-3,2′:3′,4″-terpyridine-5′,6′-diamine (Intermediate 1, 0.15 g, 0.534 mmol) in DMF (4 mL) was added and the mixture was stirred at room temperature overnight. The crude mixture was extracted between ethyl acetate and water. The organic layer was washed with 4% sodium bicarbonate aqueous solution and water, dried (MgSO4) and evaporated. The residue (0.2 g) was used in the next step without further purification.
