반응 단계

65-70% ethylamine solution (70 g, 1 mol), acetonitrile 50 mL were added into a three necked round bottom flask mounted with pressure-equalizing dropping funnel and thermometer. The solution was stirred in ice bath for 15 min to control the temperature near 0° C. Then, 2-chloro-5-(chloromethyl)pyridine (16.10 g, 0.10 mol) in 25 ml acetonitrile was added by pressure-equalizing dropping funnel in 3.5 hrs with a speed of 3 drop/min. After completion, water was added and the reaction mixture was extracted with DCM. The organic phase was collected, thereby obtaining 14 g N-((6-chloropyridin-3-yl)methyl)ethanamine as oil with 70% yield. GC-MS: m/z (%)=170 ([M]+, 20), 155 (80), 126 (100), 114 (10), 90 (12).
