Procedure

To a solution of (1-benzyl-1,2,3,4-tetrahydro-quinolin-7-yl)-(5-bromo-2-isopropyl-phenyl)-methanol (2.61 g, 5.79 mmol) in TFA (7.0 mL), Et3SiH (4.63 mL, 28.95 mmol) was added followed by triflic acid (1.0 mL, 11.5 mmol) at room temperature. The reaction mixture was stirred at room temperature for 30 min. The reaction was evaporated to dryness and neutralized by adding saturated aqueous NaHCO3 (15 mL). The resulting mixture was extraction with dichloromethane (3×30 mL). Crude product obtained after evaporation solvent was purified by using neutral alumina column chromatography to furnish 1-benzyl-7-(5-bromo-2-isopropyl-benzyl)-1,2,3,4-tetrahydro-quinoline (1.80 g).
