2-Pyridinecarboxaldehyde → (1H-Benzimidazol-2-ylmethyl)-(3-{[(1-phenyl-ethyl)-pyridin-2-ylmethyl-amino]-methyl}-benzyl)-(5,6,7,8-tetrahydro-quinolin-8-yl)-amine

Participants

Reaction Steps

Using general procedure B: Reaction of Pyridine-2-carbaldehyde (22 mg, 0.20 mmol, (1H-Benzimidazol-2-ylmethyl)-{3-[(1-phenyl-ethylamino)-methyl]-benzyl}-(5,6,7,8-tetrahydro-quinolin-8-yl)-amine (101 mg, 0.20 mmol) and sodium triacetoxyborohydride (58 mg, 0.26 mmol) in CH2Cl2 (2 mL) at room temperature under N2 for 20 h, followed by purification of the crude material by chromatography on silica gel (2:2:96 CH3OH—NH3 H2O—CH2Cl2) afforded the title compound (60 mg, 50%) as a white foam.
