実験手順
1-(3,5-Diamino-6-chloropyrazine-2-carbonyl)-2-methylisothiourea hydriodide (0.32 g, 0.82 mmol) and triethylamine (0.42 mL) were added to a solution of {2-[4-(4-amino-butyl)phenylcarbamoyl]ethyl}carbamic acid tert-butyl ester 340 (0.25 g, 0.74 mmol) in ethanol (6 mL). The reaction mixture was stirred at 65° C. for 3 hours, and cooled to room temperature. The solvent was evaporated in vacuo. The residue was purified by flash chromatography (silica gel, 10:1:0.1 to 5:1:0.1, v/v chloroform/methanol/concentrated ammonium hydroxide). The product was washed with water (2×25 mL) and dried in a vacuum oven overnight to provide 350 (0.32 g, 78%) as a yellow solid. 1H NMR (300 MHz, CD3OD) δ 1.44 (s, 9H), 1.69 (m, 4H), 2.57 (t, 2H), 2.66 (t, 2H), 3.27 (t, 2H), 3.40 (m, 2H), 7.15 (d, 2H), 7.47 (d, 2H).
