Procedure

A mixture of 4.4 g (0.01 mole) of 1-[p-(4-formyl4-pentylcyclohexyl)-phenyl]-2-(trans-4-pentyl-cyclohexyl)ethane (Example 8), 40 ml of diethylene glycol, 15 ml of 90% hydrazine and 5.5 g of potassium hydroxide is heated and the hydrazine and water are distilled off until the temperature has risen to about 230° C. The reaction mixture is then boiled for 12 hours and, when cold, 200 ml of water are subsequently added. After customary working up, 1-[p-(4-methyl-4-pentylcyclohexyl)-phenyl]-2-(trans-4-pentylcyclohexyl)-ethane is obtained.
