実験手順
A 100 mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was charged with tert-butyl 4-[[4-bromo-2-(dimethylcarbamoyl)phenyl]methyl]piperazine-1-carboxylate (130 mg, 0.300 mmol, 1.00 equiv), phenylboronic acid (113 mg, 0.930 mmol, 3.00 equiv), potassium carbonate (128 mg, 0.930 mmol, 3.00 equiv), tetrakis(triphenylphosphine)palladium (36.0 mg, 0.030 mmol, 0.10 equiv), dioxane (4 mL), H2O (0.4 mL). The resulting solution was stirred overnight at 80° C. and concentrated under reduced pressure. The residue was chromatographed on a silica gel column with ethyl acetate/petroleum ether (25/75) to provide 100 mg (79% yield) of tert-butyl 4-[[2-(dimethylcarbamoyl)-4-phenylphenyl]methyl]piperazine-1-carboxylate as light yellow oil. LCMS (ESI, m/z): 424 [M+H]+.
