实验步骤: 44 g of 2,2-dimethyl-3-(3-methylphenyl)-propionaldehyde (according to Example 3) were added in small portions under argon and at 20° C. to a pre-mix of 150 ml of isopropanol and 3.8 g of sodium borohydride. The entire mixture was stirred for 24 hours at 20° C. Excess sodium borohydride was then decomposed by the dropwise addition of 2N HCl. The reaction mixture was then taken up in 150 ml of diethyl ether and extracted with water, 2N NaOH and, again, with water. extracted with water, 2N NaOH

实验步骤: 5% Rh/C (450 mg, 15% w/w) was charged into a 50 mL autoclave vessel containing a mixture of 2,2-dimethyl-3-(3-methylphenyl)propan-1-ol (6 g, 34 mmol) in water (17 mL). The mixture was vigorously stirred under an hydrogen atmosphere (10 Bar) at 60° C. for 6 h. The reaction mixture was filtered and the filtrate was extracted with MTBE (25 mL), dried over magnesium sulphate and concentrated. The resulting crude product was distilled with a bulb-to-bulb distillation (2.5 mBar, 90° C.) to give 2,2-dimethyl-3-(3-methylcyclohexyl)propan-1-ol (5.1 g, gc purity>99%; yield 82%). containing The reaction mixture was filtered the filtrate was extracted with MTBE (25 mL) dried over magnesium sulphate concentrated The resulting crude product was distilled with a bulb-to-bulb distillation (2.5 mBar, 90° C.)
