Reaction Steps

A target compound (2.01 g, 8.224 mmol, 45.7%) was yielded in the same manner as Reference Example 10 by reacting 1-bromo-4-cyclohexylbenzene (3.34 mL, 18 mmol) with piperazine (2.01 g, 23.4 mmol), sodium t-butoxide (2.51 g, 26.1 mmol) and dichlorobis(tri-o-tolylphosphine)palladium(II) (424.4 mg, 0.54 mmol) and purifying by separation through column chromatography (CH2Cl2/MeOH, 1:1).
