With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.17217-57-1,4,4′-Dimethoxy-2,2′-bipyridine,as a common compound, the synthetic route is as follows.

General procedure: The synthesis of complexes was carried out by single potsynthesis. An anhydrous methanolic solution (10 mL) of 4-fluoro-N-salicylideneaniline (0.6456, 3 mmol) was addeddropwise to a vigorously stirred solution of 2,2?-bipyridine(0.1561, 1 mmol) in 10 mL methanol. To this solution ofligands, a methanolic solution of EuCl3 (0.2583 g, 1 mmol)was added slowly with continuous stirring. The pH of thereaction mixture obtained was adjusted to 6.0?7.0. Afteradjusting the pH, the reaction mixture was refluxed at 60 ¡ãC.The refluxing was continued for 5 h. The light yellow solutionso obtained was evaporated at room temperature to give thesolid compound which was extracted with diethyl ether. Thecompound obtained after extraction is C1 (Scheme 1).

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.17217-57-1,4,4′-Dimethoxy-2,2′-bipyridine,as a common compound, the synthetic route is as follows.

General procedure: A mixture of 10 mL methanolic solution of pyridine-2-carboxamide (0.3663 g, 3 mmol) and 10 mL methanolic solution of 4,4′-dimethoxy-2,2′-bipyridine (0.2162 g, 1 mmol) was stirred at room temperature for half an hour. Solution of EuCl3 was prepared by dissolving 1 mmol (0.2583 g) of EuCl3 in 10 mL of methanol and this solution was added to the ligands solution drop by drop with continuous stirring. The pH of resulting solution was maintained between 6 and 7. The reaction mixture was refluxed at 70 ¡ãC for 4 h. After refluxing for 4 h, the solution was cooled to room temperature and left as such overnight. Complex C1 was obtained as white precipitate which was filtered off, washed with methanol nd then dried under vacuum. The synthesis of complexes C2-C4 were done by adopting the same method as given above. Complex C2 was obtained from 3 mmol PCAO (0.3663 g), 1 mmol DMBP (0.2162 g) and1 mmol EuCl3 (0.2583 g), complex C3 was obtained from 3 mmol PDCA(0.4473 g), 1 mmol DMBP (0.2162 g) and 1 mmol EuCl3 (0.2583 g) and complex C4 was obtained from 3 mmol PM (0.3 mL), 1 mmol DMBP(0.2162 g) and 1 mmol EuCl3 (0.2583 g)., 17217-57-1
