A mixture of 3.1 g of 3-methylcyclohexanecarbonitrile and 30 ml of THF has added to it at -78° a solution of lithium diisopropylamide (prepared from 3.3 g of diisopropylamine, 30 ml of THF and 19 ml of 1.6-molar butyllithium solution in hexane) and then a solution of 9.7 g of 1-bromo-2-(4'-pentylbiphenyl-4-yl)ethane in 30 ml of THF. Working up as in Example 1 gives 1-(1-cyano-3-methylcyclohexyl)-2-(4'-pentylbiphenyl-4-yl)ethane, m.p. 73°.
