With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1273-82-1,Aminoferrocene,as a common compound, the synthetic route is as follows.
The aminoferrocene compound (300 mg, 1.49 mmol) obtained in Preparation Example 1, 4-bromobiphenyl (380 mg, 1.64 mmol), palladium acetate (Pd(OAc)2, 17 mg, 0.075 mmol), 1,1?-bis(diphenylphosphino)ferrocene (dppf, 67 mg, 0.12 mmol), and sodium tert-butoxide (NaOtBu, 577 mg, 6 mmol) were mixed in toluene (5 ml, as a solvent). A reaction was conducted at 90 C. for 72 hours. The reaction was poured into pure water and was extracted five times with ethyl ether (60 ml). The organic layer thus obtained was dried using anhydrous magnesium sulfate. After the solvent was removed, purification was conducted by column chromatography (eluent: n-butane/ethyl acetate=3/2 (v/v)) to obtain compound BPAFc in the form of an orange solid (yield: 68%). The structure of compound BPAFc is shown in Scheme II.
1273-82-1 Aminoferrocene 72747180, airon-catalyst compound, is more and more widely used in various.
