Procedure

Formic acid (1.5 g, 33 mmol) and toluene (10 ml) were added to the above 4-(4-(1,3-dioxan-2-ylethyl)cyclohexyl)-1-(2-(4-trifluoromethylphenyl)ethyl)cyclohexane (1.46 g, 3.23 mmol), followed by refluxing the mixture for 5 hours, washing the organic layer successively with a saturated, aqueous solution of sodium bicarbonate and water, drying over magnesium sulfate, and distilling off the solvent, to obtain 3-(4-(4-(2-(4-trifluoromethylphenyl)ethyl)cyclohexyl)cyclohexyl)propanal (1.21 g, 3.07 mmol). Yield: 95.0%.

Workup

  1. temperatureby refluxing the mixture for 5 hours
  2. washwashing the organic layer successively with a saturated, aqueous solution of sodium bicarbonate and water
  3. dry with materialdrying over magnesium sulfate
  4. distillationdistilling off the solvent
