Participants

Reaction Conditions

Reaction Steps

1-Bromo-4-t-butylbenzene (2.38 mL, 14 mmol), piperazine (1.8 g, 21 mmol), sodium t-butoxide (1.95 g, 20.3 mmol) and dichlorobis(tri-o-tolylphosphine)palladium(II) (330.1 mg, 0.42 mmol) were dissolved in anhydrous toluene and reacted for 3 hours while heating at 100° C. After identifying complete disappearance of 1-bromo-4-t-butylbenzene by TLC, the reaction solution was filtered with celite. The filtrate was concentrated and purified by separation through column chromatography (CH2Cl2/MeOH, 1:1). A target compound (1.47 g, 6.732 mmol, 48.2%) was yielded.
