Versuchsvorschrift

5′-(3-Furoylamino)-2′-methyl-1,1′-biphenyl-4-carboxylic acid (50 mg, 0.156 mmol), TBTU (60 mg, 0.186 mmol), 1-(3-aminopropyl)-4-methylpiperazine (25 mg, 0.156 mmol) and DIPEA (81 μl, 0.467 mmol) in DMF (1 ml) were stirred at room temperature for 2 h. The DMF was evaporated under vacuum and the residue dissolved in chloroform and filtered through an aminopropyl SPE (3 g). The filtrate was purified by flash chromatography on silica, eluting with DCM/ethanol/ammonia (110:8:1), which after evaporation of the solvents under vacuum gave N-(4′-([3-(4-methylpiperazin-1-yl)propylamino]carbonyl)-6-methyl-1,1′-biphenyl-3-yl)-3-furamide (12 mg, 17%).
