Mode opératoire

Using General Procedure B: To a stirred solution of N′-(1H-benzimidazol-2-ylmethyl)-N′-(5,6,7,8-tetrahydro-8-quinolinyl)-1,4-benzenedimethanamine (133 mg, 0.34 mmol) and 3-chloro-5-(trifluoromethyl)-pyridine-2-carboxaldehyde (66 mg, 0.32 mmol) in CH2Cl2 (5 mL) was added NaBH(OAc)3 (93 mg, 0.44 mmol) and the mixture was stirred at room temperature for 16 h. Purification of the crude material by radial chromatography on silica gel (1 mm plate, CH2Cl2/MeOH/NH4OH, 75:1:1) afforded the desired amine (48 mg, 26%) as a yellow foam.
