Reaktionsschritte

To a stirred solution of 1-phenyl-2-propanol (2.18 g, 16.0 mmol) in CH2Cl2 (100 mL) is added Dess-Martin periodinane (50 mL, 15 wt % solution in methylene chloride) at 0° C. After stirring at 0° C. for 1 h, the mixture is warmed to RT and stirred for 1.5 h. To the reaction mixture is added saturated NaHCO3 (200 mL) and stirred at RT for 20 min. The mixture is filtered through Celite and the organic phase is washed with water and brine then dried over MgSO4. The solvent is removed under reduced pressure and the crude material is purified by flash chromatography to afford the title compound as a colorless oil: (M+1)+=135.
