실험 절차

79.6 g (0.63M) of the optically active alcohol (V) obtained in 1-4) above was dissolved in 300 ml of methylene chloride and the resulting solution was added dropwise to a suspension of 304 g (0.81M) of pyridine dichromate in 700 ml of methylene chloride at room temperature. Then the resulting mixture was stirred for three days. The obtained reaction mixture was diluted with 1 l of diethyl ether and filtered through celite. The filtrate was dried over anhydrous magnesium sulfate and the solvent was evaporated. The residue was distilled under reduced pressure to give 50.4 g (theoretical yield: 64.5%) of the aimed compound (VI) as a colorless oily material. b.p.: 70° C./20 mmHg.
