1-Bromo-4-iodobenzene → 4-Benzyl-1-(4-bromophenyl)piperidine

関与物質

反応手順

A mixture of 1-bromo-4-iodo benzene (0.500 g), 4-benzylpiperidine (0.25 mL), sodium-tert-butylate (0.238 g), tris(dibenzylideneacetone)dipalladium (0.016 g) and 2,2′-bis/diphenylphosphino)-1,1′-binaphtyl racemate (0.018 g) is dissolved in tetrahydrofuran and stirred at room temperature overnight. The reaction mixture is concentrated and the resulting residue is loaded on Celite and purified by silica gel chromatography (4:1 hexanes/ethyl acetate) to give 4-benzyl-1-(4-bromo-phenyl)-piperidine as a light yellow syrup. MS (m/z): 331 (M+1).
