Versuchsvorschrift

34.5 g (0.15 mol) of the compound obtained in Step A are dissolved in 300 ml of methanol. 35 g (4 eq) of potassium hydroxide dissolved in 35 ml of water are added with vigorous stirring. After 3 hours at room temperature, the reaction mixture is hydrolysed over a mixture of ice/concentrated hydrochloric acid. The creamy white precipitate which forms is filtered off, washed several times with ice-cold water and dried over P2O5 using a dessicator. The title alcohol is recrystallised from a mixture of CH2Cl2/cyclohexane to yield white needles.
