Reaction Steps

To a solution of ethyl 4,6-dichloronicotinate (4.4 g, 20 mmol) in CH3CN (50 mL) was added dropwise a solution of ethylamine in water (65%, 2.7 g, 39 mmol) at 0° C., then the resulting mixture was stirred at RT overnight. The reaction was concentrated and the residue was washed with water to give ethyl 6-chloro-4-(ethylamino)nicotinate (3.9 g, 91% yield). 1H NMR (400 MHz, DMSO-d6): δ 8.51 (s, 1 H), 8.08 (s, 1 H), 6.53 (m, 1 H), 4.19 (q, J=7.2 Hz, 2H), 2.78 (q, J=7.2 Hz, 2 H), 1.28 (t, J=7.2 Hz, 3 H), 1.13 (t, J=7.2 Hz, 3 H); MS (ESI) m/z: 229.1[M+H]+.
