実験手順

12N HCl (5 mL) was added to {4-[4-(carbamoylmethylamino)phenyl]butyl}carbamic acid tert-butyl ester 390 (0.2 g, 0.62 mmol). The reaction was stirred at room temperature for 1 hour. The solvent was evaporated in vacuo. The residue was purified by flash chromatography (silica gel, 4:1:0.1 chloroform/methanol/concentrated ammonium hydroxide, v/v) to provide 400 (0.10 g, 70%) as a white solid. 1H NMR (300 MHz, CD3OD) δ 1.55 (m, 4H), 2.50 (t, 2H), 2.68 (t, 2H), 3.70 (s, 2H), 6.52 (d, 2H), 6.97 (d, 2H).
