実験手順

To a solution of N,N-dicyclohexylcarbodiimide (2.08 g, 10 mmol) in dry tetrahydrofuran (20 ml) was slowly added at -10° C. a solution of N-(4-bromobenzyl)-N-(pyridin-2-yl)-propane-1,3-diamine (3.20 g, 10 mmol) and carbondisulfide (4.3 ml, 70 mmol) in dry tetrahydrofuran (20 ml) under an atmosphere of nitrogen. The mixture was stirred at -10° C. for 3 h and for 48 h at room temperature. The reaction mixture was filtered and the solvent evaporated in vacuo. The residue (5.29 g) was extracted with diethyl ether (3×20 ml) and the combined organic extracts were evaporated in vacuo affording 3.2 g (88%) of N-(4-bromobenzyl)-N-(3-isothiocyanatopropyl)-N-(pyridin-2-yl)amine as an oil.
