To a suspension of 238 g (1.1 mole) of pyridinium chlorochromate and 800 ml of methylene chloride was added 79.3 g (0.34-mole) of 2-benzyl-4-chlorobenzyl alcohol. The mixture was stirred at room temperature for 2 hr. The chromium salts were precipitated by the addition of 2.4 liters of 1:1 ether:petroleum ether, and the precipitate was removed by filtration through Celite. The solvent was removed at reduced pressure to give a yellow oil, which was used without further purification.
