Ethyl 3-oxo-hexanoate (100 g, 0.63 mmol) was dissolved in 400 ml of diethyl ether and ammonia was bobbled through the solution for 8 hours. During the reaction magnesium sulfate was added in portions as a drying agent. When no starting material was detected on TLC, the mixture was filtered, and the solvent was evaporated to afford 75 g (76%) of ethyl 3-amino-hex-2-enoate as an oil. 1H--NMR (CDCl3, 200 MHz) δ: 0.95 (t, 3 H); 1.25 (t, 3 H); 1.58 (sextet, 2 H); 2.09 (t, 2 H); 4.11 (q, 2 H); 4.52 (s, 1 H).
