実験手順

To a solution of 4,4-dimethylcyclohexanone (3.0 g, 0.024 mole) and hydroxylamine hydrochloride (2.2 g, 0.031 mole) in ethanol (15 mL) and water (20 mL) at room temperature was added a solution of sodium carbonate (3.3 g, 0.031 mol) in water (10 mL), dropwise. The mixture was heated under reflux for 3 hr, cooled to room temperature and ethanol was removed in vacuo. The aqueous residue was extracted several times with ethyl acetate, combined extracts were dried over MgSO4 and concentrated in vacuo affording the title compound as a white solid, used without further purification. 1H NMR (400 MHz, DMSO-d6) δ ppm 0.93 (s, 6H), 1.28 (t, J=6.6 Hz, 2H), 1.35 (t, J=6.6 Hz, 2H), 2.11 (t, J=6.6 Hz, 2H), 2.36 (t, J=6.6 Hz, 2H), 10.12 (s, 1H).
