الإجراء التجريبي

Under nitrogen atmosphere, to a solution of 1.48 g (5.15 mmol) of 4-[3-(2-aminobenzoylamino)propylthio]pyridine in 30 ml of tetrahydrofuran, 1.84 g (10.3 mmol) of 1,1'-thiocarbonyldiimidazole was added, and the mixture was stirred at room temperature for 64 hours. The solvent was distilled off and the residue was washed with chloroform/ether to give 1.16 g of the desired product (68.5% yield, pale brown crystals).
