Procedure

To 50 ml of dry acetone, 4.0 g (0.013 m) of the product of Example 2, 2.2 g (0.016 m) of powdered anhydrous potassium carbonate, and 1.4 ml (0.016 m) of allyl bromide was added in succession and the mixture stirred overnight at room temperature. The mixture was poured into 300 ml of ice water with stirring. The aqueous layer was decanted and the residue suspended in fresh ice cold water, stirred and filtered to give a yellow semisolid product. This was purified by stirring in hexane to give a yellow powder 1.8 g (39%), m.p. 78°-81°.
