実験手順

To a mixture of N-[methylsulfanyl-(4-(pyridin-2-yl)piperazin-1-yl)methylene]-benzamide (2.9 g, 8.52 mmol) in pyridine (50 ml) was added N1-(4-bromobenzyl)-N1-(pyridin-2-yl)-propane-1,3-diamine (3 g, 9.37 mmol) and the reaction mixture was heated at reflux for 18 h. The volatiles were evaporated in vacuo and the residue dissolved in dichloromethane (100 ml) and evaporated in vacuo. The residue was purified by column chromatography on silica gel (600 ml) using first a mixture of ethyl acetate/triethylamine 95:5 (1 l) followed by a mixture of ethyl acetate/methanol/triethylamine 90:5:5 as eluents affording 2.95 g of N-[[3-[N-(4-bromo-benzyl)-N-(pyridin-2-yl)amino]propylamino]-(4-pyridin-2-yl-piperazin-1-yl) methylene]benzamide as a foam.
