With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.71071-46-0,Dimethyl [2,2′-bipyridine]-4,4′-dicarboxylate,as a common compound, the synthetic route is as follows.
71071-46-0, General procedure: A solution of cis-RuII(bpz)2Cl2 (100 mg, 0.205 mmol) and AgNO3 (77 mg, 0.453 mol) in water (25 mL) was heated at reflux for 48 h. After cooling to room temperature, the mixture was filtered through Celite to remove AgCl, and the filtrate was evaporated to dryness. The residue was dissolved in DMF (15 mL) and the solution purged with argon for 15 min. 4,4?-bis(trifluoromethyl)-2,2?-bipyridyl (121 mg, 0.414 mmol) was added and the mixture heated at 100 °C for 24 h under argon. After cooling to room temperature, the solution was evaporated under vacuum to a small volume and diethyl ether (150 mL) added. The precipitate was filtered off and dissolved in a minimum of cold water to which solid NH4PF6 was added. The solid was filtered off and purified by column chromatography as for 1 to give an orange solid. Yield: 73 mg (35percent).
The synthetic route of 71071-46-0 has been constantly updated, and we look forward to future research findings.
