Procedure

Using General Procedure B: To a stirred solution of 1-(2-methoxy-phenyl)-ethanone (69 uL, 0.50 mmol), N′-(1H-benzimidazol-2-ylmethyl)-N′-(5,6,7,8-tetrahydro-8-quinolinyl)-1,4-benzenedimethanamine (200 mg, 0.50 mmol) and AcOH (0.10 mL, 1.4 mmol) in THF (5 mL) was added NaBH(OAc)3 and the mixture was stirred at room temperature for 48 hours. Purification of the crude light yellow foam (267 mg) by column chromatography on silica gel (100:1:1—CH2Cl2:MeOH:NH4OH) followed by radial chromatography on silica gel (100:1:1—CH2Cl2:MeOH:NH4OH) afforded the desired product (83 mg, 27%) as a white foam.
