Reaction Conditions

Reaction Steps

A mixture of bromobenzene (300 mg), (S)-2-methylpiperazine (230 mg), (S)-(−)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (BINAP) (48 mg), sodium tert-butoxide (266 mg), tris-(dibenzylideneacetone)dipalladium(0) (26 mg) and toluene (15 ml) was stirred at 100° C. for 4 hours under a nitrogen atmosphere. The mixture was cooled to room temperature and saturated aqueous sodium hydrogencarbonate solution was added thereto. The organic layer was separated, washed with brine and dried over magnesium sulfate. The solvent was removed under reduced pressure. The obtained crude product was purified by silica gel column chromatography (chloroform-methanol 20:1) to give the title compound in a pure form.
