Procedure

N-(3-aminobenzyl)-1,1′-biphenyl-4-carboxamide (20 mg, 0.07 mmol) was dissolved in acetic acid (0.5 ml). 3-Carboxybenzaldehyde (14 mg, 0.09 mmol) was added and then sodium borohydride (11 mg, 0.28 mmol) was added. The mixture was stirred at room temperature for 2 hours and evaporated to dryness. DCM was added into the residue. The mixture was loaded on a column (ISOLUTE® SI, 500 mg/3 ml). It was eluted with DCM, MeOH/DCM (0.5:99.5) and then MeOH/DCM (1:99). The product fractions were combined and the solvent was removed, Re-chromatography of the residue on a column (ISOLUTE® SI, 1 g/6 ml) using DCM, MeOH/DCM (0.5:99.5) and then MeOH/DCM (1:99) as eluant gave 9 mg the desired product, yield 31%.
