Procedure

The title product of Example 2 (3.0 g, 0.0126 mole) was reacted with 3-chloro-2-butanone (1.27 ml) and triethylamine (1.7 ml) in ethyl ether (20 ml) at room temperature overnight. The mixture was filtered, the crystals washed with ethyl ether and the combined filtrates evaporated in vacuo. The crude product was chromatographed on silica then recrystallized from ethyl acetate/hexane to give the title compound m.p. ca. 94°-97° C.
