반응 단계

A solution of 2-methylimidazole (0.820 g, 10.0 mmol) in DMF (10 mL) was cooled in an ice/water bath and sodium hydroxide (1.00 g, 25.0 mmol) added. The resulting mixture was stirred for 30 min, then 2-chloropropylamine hydrochloride (1.30 g, 10.0 mmol) added in one portion. The resulting suspension was then stirred for 16 h during which time the reaction slowly warmed to room temperature. After this time the mixture was poured into water (500 mL) and the mixture extracted with ether (3×100 mL). The combined ether extracts were dried over sodium bicarbonate, filtered and concentrated under reduced pressure to afford 0.726 g (52% yield) of 3-(2-methylimidazol-1-yl)propylamine as a yellow oil. 1H NMR (300 MHz, CD3OD) δ 7.00 (d, J=1.4 Hz, 1H), 6.79 (d, J=1.4 Hz, 1H), 3.97 (t, J=7.3 Hz, 2H), 2.63 (t, J=7.1 Hz, 2H), 2.35 (s, 3H), 1.87 (m, 2H).
