Procedure

A three-necked 250 ml flask is heated, desiccated, and purged with argon. Tetrahydrofuran (50 ml) is injected via syringe and the flask is cooled to -78° C. To this is added 8.33 ml (0.0133 mole) of 1.6 M n-butyl lithium via syringe followed by 2 ml (0.0133 mole) of diisopropyl amine. To 10 ml of dried tetrahydrofuran, 5 g (0.0133 mole) of the product of Example 2 is added and the solution is injected into the reaction mixture. The mixture is stirred for an hour. Allyl bromide, 2.4 g (0.02 mole) is injected into the flask and the mixture is stirred for 90 minutes at room temperature.
