Procedure

A solution of (6-aminomethyl-quinolin-2-yl)-(2-methoxy-benzyl)-amine (example 85, step B) (390 mg, 1.33 mmol), 4-fluorobenzaldehyde (181.5 mg, 1.46 mmol) and acetic acid (319.3 mg, 5.32 mmol) in 1,2-dichloroethane (15 ml) was stirred at room temperature for 30 min. Afterwards sodium triacetoxy-boron hydride (657 mg, 2.79 mmol) was added, the reaction mixture was allowed to stir for 60 h at room temperature, poured into ice/saturated NaHCO3 solution (30 ml) and extracted with dichloromethane (2×40 ml). The combined organic layers were washed with brine (30 ml), dried (MgSO4) and evaporated. The crude product was purified by flash chromatography (ethyl acetate/heptane) on silica gel to yield the title compound as colorless oil (284 mg, 53%).
