Procedure

Using General Procedure B: A solution of 1-methyl-2-imidazole carboxaldehyde (27.5 mg, 0.25 mmol) and (4-aminomethyl-benzyl)-(1H-benzoimidazol-2-ylmethyl)-(5,6,7,8-tetrahydro-quinolin-8-yl)-amine (100 mg, 0.25 mmol) in MeOH (2.0 mL) was stirred overnight at room temperature. NaBH4 (37.5, 0.75 mmol) was added and the resultant mixture stirred for an additional 15 minutes. Purification of the crude white foam by column chromatography on silica gel (CH2Cl2[MeOH/NH4OH, 50:1:1) followed by radial chromatography on silica gel (CH2Cl2/MeOH/NH4OH, 200:3:2) afforded the desired amine (83 mg, 67%) as a white foam.
