Reaction Steps

Under a nitrogen atmosphere, a mixture of 2-{[3-(trifluoromethyl)anilino]methylene}malonate (80 g, 0.24 mol) and Dowtherm A was heated to 240° C. and then stirred for 3 hours. The reaction mixture was allowed to cool to ambient temperature and then stirred for 16 hours. The solids were isolated by filtration then washed with hexane to provide 47.5 g of ethyl 4-hydroxy-7-(trifluoromethyl)-3-quinolinecarboxylate as an off-white solid.
