Reaction Steps

A mixture of 1-[(4-bromophenyl)carbonyl]-4-(2-tert-butylphenyl)piperazine (1.0 g, 2.49 mmol), [4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]acetic acid (0.653 g, 2.49 mmol), 2 M sodium carbonate solution (3 mL, 6.0 mmol), and tetrakis(triphenylphosphine)palladium(0) (0.150 g, 0.13 mmol) in tetrahydrofuran (5 mL) and toluene (20 mL) was stirred at 120° C. for 16 h. 6 M hydrochloric acid solution was added and the mixture was extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure to afford a solid. The solid was dissolved in ethanol-ethyl acetate and recrystallized to obtain a solid (0.3 g, 26%).
