Reaction Steps

A dried Radley tube was charged with rac-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl (6.32 mg, 10.15 µmol), Tris(dibenzylideneacetone)dipalladium(0) (4.65 mg, 5.08 µmol) and Sodium tert- butoxide (34.1 mg, 0.36 mmol). Argon atmosphere was introduced and toluene (3ml) was added followed by 7-bromobenzofuran (50mg, 0.25 mmol) and 1-phenethylpiperazine (48.3 mg, 0.25 mmol). The reaction mixture was heated at reflux over night. 2010-03-25 The reaction mixture was filtered, concentrated and purified by flash chromatography (Isolute Si 10g, heptane: ethyl acetate; 4:1) to give 1-(benzofuran-7-yl)-4-phenethylpiperazine (48.3 mg, 62.1 %)
