Guo, Libing published the artcileSynthesis of N-(4-biphenyl)-(9,9-dimethyl-2-fluorenyl)amine, Category: bromides-buliding-blocks, the publication is Huaxue Tongbao (2010), 73(8), 750-752, database is CAplus.
2-Bromofluorene was prepared from fluorene and benzyltrimethylammonium tribromide in dichloromethane-methanol solution at room temperature, followed by a reaction with iodomethane in THF in the presence of potassium tert-butanolate and formation of 9,9-dimethyl-2-bromo-9H-fluorene. The synthesis of the target compound was achieved by a Buchwald-Hartwig reaction of the above-mentioned aryl bromide with [1,1′-biphenyl]-4-amine and the product thus obtained was confirmed by 1H-NMR, 13C-NMR, MS, IR spectra and elemental anal.
