To a solution of the oxime formed in Example 1 (1 g, 8.25 mmol) in HCl (0.5 M in dioxane; 18.16 ml, 9.08 mmol) and DMF (40 ml) was added oxone (2.79 g, 4.54 mmol) and the resulting mixture was stirred overnight at room temperature. The reaction was partitioned between diethylether and water and the layers were separated. The organic layer was washed with saturated ammonium chloride, dried over sodium sulfate, then concentrates in vacuo using a room temperature water bath. The resulting low boiling liquid was carried on directly to the next step. 1H NMR (CDCl3) δ 1.0-2.2 (m, 10H), 2.35 (m, 1H), 7.8 (bd, 1H).
