Reaction Conditions

Reaction Steps

Chromium trioxide (6.0 g., 0.06 mole) is added to a mechanically-stirred solution of dry pyridine (9.49 g., 0.12 mole) in methylene chloride (150 ml.) maintained at 0°-5° C. under a nitrogen atmosphere. The resulting reaction mixture is warmed to 25° C., stirred at 25° C. for 1/3 hour, and treated with a solution of 3(S)-benzyloxy-1-octanol (2.37 g., 0.01 mole) in methylene chloride (2 ml.) which initiates precipitation of a black, intractable precipitate. After stirring at 25° C. for 1/4 hour, the solution is decanted, and the insoluble precipitate washed with ether (200 ml.). The combined decantates are washed successively with 5% sodium hydroxide (3 × 100 ml.), 5% hydrochloric acid (100 ml.), and 5% aqueous sodium bicarbonate (100 ml.); dried over magnesium sulfate; and filtered. In vacuo evaporation of the filtrate affords the title compound as a pale yellow oil.
