실험 절차
A mixture of N-[4-(benzyloxy)butyl]-N-propylamine (2.31 g, 10.44 mmol), 3-(ethoxycarbonyl)-5-methylbenzoic acid (2.18 g, 10.44 mmol), HOBt (1.56 g, 11.49 mmol), N-methylmorpholine (1.37 mL, 12.52 mmol), and EDC (2.20 g, 11.49 mmol) in DMF (12 mL) is stirred at 20–25 degrees C. for 18 hours. The reaction mixture is diluted with ethyl acetate (80 mL) and washed with water (2×20 mL), hydrochloric acid (1 N, 20 mL), saturated sodium bicarbonate (20 mL) and saline (20 mL), dried over magnesium sulfate, filtered, and concentrated under reduced pressure. Purification by flash chromatography (silica; hexanes/ethyl acetate,1/1) gives ethyl 3-{[[4-(benzyloxy)butyl](propyl)amino]carbonyl}-5-methylbenzoate (1.79 g), NMR (500 MHz, DMSO-d6): delta7.80, 7.64, 7.40, 7.38–7.16, 4.50–4.43, 4.34–4.29, 3.53–3.30, 3.20–3.06, 2.41–2.36, 1.70–1.40, 1.36–1.29, 0.94–0.84 and 0.82–0.72; APCI-MS (m/z) [M+H]+=412.
