Reaction Steps
A target compound (1.03 g, 5.041 mmol, 40.2%) was yielded in the same manner as Reference Example 10 by reacting 5-bromo-1,2,4-trimethylbenzene (2.5 g, 12.556 mmol) with piperazine (4.32 g, 50.224 mmol), sodium t-butoxide (1.75 g, 18.206 mmol) and dichlorobis(tri-o-tolylphosphine)palladium(II) (295.5 mg, 0.37 mmol) and purifying by separation through column chromatography (CH2Cl2/MeOH, 1:1).
