Reaction Steps

5'-Carboxy-2'-hydroxy-4-[2-(2-quinolinyl)ethenyl]chalcone (1 eq.) and selenium dioxide (2.2 eq.) were refluxed for 8 hours in dioxane. The reaction mixture was allowed to cool down to room temperature. The resulting crystals were collected by filtration. The thus-obtained crude crystals were recrystallized form DMF, whereby the title compound represented by the following formula was obtained (yield: 28%). ##STR46##
