실험 절차

1-(3,5-Diamino-6-chloropyrazine-2-carbonyl)-2-methylisothiourea hydriodide (0.13 g, 0.33 mmol) was added to a solution of 2-[4-(4-aminobutyl)phenoxy]-N,N-bis-(2-hydroxyethyl)acetamide 26 (0.09 g, 0.3 mmol), triethylamine (0.12 mL), and ethanol (1.7 mL). The reaction mixture was stirred at 60° C. for 3 h. The solvent was evaporated in vacuo. The residue was triturated with water and then purified by flash chromatography (silica gel, 20-10:1:0-0.2 CH2Cl2/methanol/concentrated ammonium hydroxide, v/v) to provide 2-(4-{4-[N′-(3,5-diamino-6-chloropyrazine-2-carbonyl)guanidino]butyl}-phenoxy)-N,N-bis-(2-hydroxyethyl)acetamide 27 (0.1 g, 64%) as a yellow solid. mp 114-116° C. 1H NMR (300 MHz, CD3OD) δ 1.70 (m, 4H), 2.60 (m, 2H), 3.32 (m, 2H), 3.50 (m, 4H), 3.70 (m, 4H), 4.81 (s, 2H), 6.85 (d, 2H), 7.10 (d, 2H). m/z (ESI): 523 [C22H31ClN8O5+H]+.
