To a solution of cyclohexanecarbaldehyde (4 ml, 33.02 mmol) in CH2Cl2 (100 ml) at room temperature was added hydroxylamine hydrochloride (2.76 g, 39.62 mmol) followed by Et3N (5.52 ml, 39.62 mmol) and the reaction was stirred overnight. The resulting mixture was partitioned between CH2Cl2 and H2O and the layers were separated. The organic layer was dried over Na2SO4, concentrated in vacuo and used directly for the next step. 1H NMR (CDCl3) δ 1.0-2.0 (m, 10H), 3.0 (m, 1H), 6.6 (d, 0.5H), 7.4 (d, 0.5H), 8.2 (bs, 1H).
