To a solution of 5.26 g. of 1-iodo-3-(p-anisyldiphenylmethoxy)-trans-1-octene (Example 956) in 10 ml. of toluene, cooled to -78° C., is added under an inert atmosphere 1 molar equivalent of n-butyllithium dissolved in hexane. The reaction mixture is allowed to warm to -40° C. and is maintained at that temperature for 1 hour to yield a hydrocarbon solution of 3-(p-anisyldiphenylmethoxy)-trans-1-octenyllithium.
