Versuchsvorschrift

Using General Procedure B: To a stirred solution of 2-methyl-pyridine-3-carbaldehyde (75 mg, 0.62 mmol), N′-(1H-benzimidazol-2-ylmethyl)-N′-(5,6,7,8-tetrahydro-8-quinolinyl)-1,4-benzenedimethanamine (246 mg, 0.62 mmol) and AcOH (40 uL, 0.62 mmol) in THF (6.2 mL) was added NaBH(OAc)3 (394 mg, 1.86 mmol) and the mixture was stirred at room temperature overnight. Purification of the crude white foam (280 mg) by column chromatography on silica gel (200:3:1—CH2Cl2:MeOH:NH4OH) afforded the desired product (116 mg, 37%) as a colorless syrup.
