4-benzyl-N,N-diphenylaniline (5.0 g, 14.9 mmol) was dissolved in tetrahydrofuran (80 mL) under a nitrogen atmosphere. n-Butyllithium (10.3 mL, 16.4 mmol) was slowly added to the reaction solution at −78° C., and then the reaction mixture solution was stirred at room temperature for 1 hour. Also, the reaction mixture solution with chlorotrimethylsilane (1.8 g, 16.4 mmol) added thereto was stirred at room temperature for 1 hour. The reaction mixture solution was passed through a silica gel column by using hexane as an eluant. After the solvent is removed, the residue material was dried in vacuum to thereby a white solid (5.1 g, yield: 84%).
