실험 절차

5-[(3-Bromophenylamino)methylene]-2,2-dimethyl-[1,3]dioxane-4,6-dione (32.6 g, 0.100 mol) was heated at 250° C. in DOWTHERM A heat transfer fluid for one hour, and then the reaction was allowed to cool to ambient temperature. A precipitate formed upon cooling and was isolated by filtration and washed with diethyl ether to provide 7-bromoquinolin-4-ol and 5-bromoquinolin-4-ol in a 2:1 ratio.
