실험 절차

A solution of 59.0 g. of trans-4-n-pentylcyclohexane carbinol in 100 ml. of ether is added to a suspension of 125 g. of pyridinium chlorochromate in 900 ml. of methylene chloride and the mixture is stirred at room temperature for 2 hours. The mixture is then diluted with 400 ml. of ether, stirred for a further 15 minutes and the solution is decanted off from the tarry precipitate. The precipitate is back-washed with ether. The combined organic solutions are filtered through a Florisil column. The trans-4-n-pentylcyclohexane carboxaldehyde obtained after evaporation of the filtrate is used directly in the next step.
