실험 절차

To the solution of 2-ethyl-1-(hydroxyimino)cyclohexane (6.8 g, 48.5 mmol) in ethanol (75 mL) were added sodium pieces (about 8.0 g) in portions, and the reaction was heated to reflux at 110° C. overnight. More sodium pieces were added, and the reaction was stirred for another 6 hours. The reaction was treated with concentrated HCl (12 M, 4.0 mL) in water (25 mL). Ethanol was removed in vacuo. The aqueous layer was washed with ether (10 mL), and treated with aqueous KOH (25 mL) and extracted with ether (3×20 mL). The combined organic extracts were washed with brine (20 mL), dried over sodium sulfate, and concentrated in vacuo to give 2-ethylcyclohexylamine as an off-white oil.
