Procedure
To a 200 mL round bottom flask containing the product of Example 32C (1.50 g, 8.71 mmol) and DMP (4.06 g, 9.58 mmol) (Aldrich) was added methylene chloride (100 mL) and the reaction mixture was stirred for 1 hr at room temperature. The reaction mixture was quenched with saturated NaHCO3 and extracted with EtOAc (200 mL), dried (NaSO4), filtered, and concentrated in vacuo. The residue was purified on SiO2 with hexane/ethylacetate 0-20% to afford a colorless oil (1.12 g) in 76% yield. 1H NMR (300 MHz, CDCl3) δ ppm 4.20-3.95 (m, 4H), 2.63-1.97 (m, 6H), 1.94-1.74 (m, 1H), 1.04-0.83 (m, 3H). MS (DCI+) M/Z 171 (M+H)+.
