Procedure

2-(2,4,4-Trimethylcyclopentyl)acrylonitrile 5 is placed in toluene at 10° C. under an inert atmosphere. 1.2 eq. of Dibal (diisobutylaluminum hydride) are added thereto dropwise. The reaction medium is stirred at ambient temperature for a few hours and is then poured onto a 20:40:40 mixture of acetic acid, water and ice. The aqueous phase is extracted once with toluene. The combined organic phases are washed with a sodium bicarbonate solution and then with an aqueous sodium chloride solution. After drying over magnesium sulfate, filtering through paper and evaporating the solvent, the crude product, obtained in the form of two diastereomers in proportions of 70:30, is distilled under reduced pressure.
