Mode opératoire

Using General Procedure B: To a stirred solution of 1,2,3,4-tetrahydroisoquinoline (49 mg, 0.37 mmol), 4-{[(1H-benzimidazol-2-ylmethyl)-(5,6,7,8-tetrahydro-quinolin-8-yl)-amino]-methyl}-benzaldehyde (140 mg, 0.34 mmol), and AcOH 0.020 mL, 0.35 mmol) in THF (3.5 mL) was added NaBH(OAc)3 (94 mg, 0.44 mmol) and the mixture was stirred at room temperature for 2 h. Purification of the crude material by column chromatography on silica gel (500:5:1 CH2Cl2/MeOH/NH4OH) afforded a colourless foam (137 mg).
