Versuchsvorschrift
2 g (7.46 mmol) of 3-methyl-heptadecan-2-one are dissolved in 20 ml of ethanol and the solution is treated, at 0° C., with 0.28 g (7.46 mmol) of sodium borohydride. Stirring is continued for two hours at 0° C. and for two hours at room temperature. The mixture is subsequently concentrated under reduced pressure, the concentrate is taken up in cyclohexane/water, and the aqueous phase is extracted three times using cyclohexane. After the extract has been dried and concentrated, 2 g (99% of theory) of 3-methyl-heptadecan-2-ol are obtained as pure substance.
