Reaction Steps

To a stirred solution of crude (III) in benzene (35 ml) at room temperature was added 2,3-dichloro-5,6-dicyano-1,4-benzoguinone (1.0 g, 0.0048 mmol) all at once, and the mixture was allowed to stir overnight at ambient temperatures. The mixture was then filtered, the volatiles removed (hi-vac), and the residue chromatographed on silica gel (methylene chloride/hexane) to yield 0.35 g of the title compound. M.S. (M+)=300; NMR: consistent. ##STR25##
