実験手順

{2-[4-(4-Aminobutyl)phenoxy]ethyl}carbamic acid tert-butyl ester 2 (1.7 g, 5.5 mmol), 1-(3,5-diamino-6-chloropyrazine-2-carbonyl)-2-methylisothiourea hydriodide (2.6 g, 6.6 mmol), and triethylamine (3.1 mL) were combined in THF (18 mL). The reaction was stirred at reflux under argon for 1.5 h. The product mixture was allowed to cool, and the solvent was evaporated. Chromatography (silica gel, methylene chloride/methanol/concentrated ammonium hydroxide, 100:10:1) afforded 2.65 g (92%) of the pure product as a yellow foamy solid. 1H NMR (300 MHz, CDCl3) δ 1.44 (s, 9H), 1.62 (m, 2H), 1.61 (m, 2H), 1.75 (br s, 2H), 2.56 (t, 2H), 2.71 (t, 2H), 3.51 (m, 2H), 3.99 (t, 2H), 5.07 (br s, 1H), 6.80 (d, 2H), 7.08 (d, 2H).
