Participants

Reaction Steps

A solution of 3 g (20 mmol) of 2-methylindene (C. F. Koelsch, P. R. Johnsen, J. Am. Chem. Soc. 65, 567, (1943)) in 50 ml of diethyl ether is cooled to -78° C. and admixed with 14.6 ml of a 1.58 molar solution of n-butyllithium in n-pentane. The solution is warmed to room temperature and the 2-methylindenyllithium formed is filtered off and dried under reduced pressure. The yield is 2.5 g (91.9% of theory).
