To a solution of 5-methyl-2-(trifluoromethyl)-3-furancarboxylic acid (20 g, 103 mmol) in quinoline (36 ml) was added copper (I) sulfate (1 g, 6.3 mmol). While bubbling nitrogen, the mixture was immersed in an oil bath at 230° C. until gas generation ceased. The generated gas was collected and distilled again to give 2-methyl-5-(trifluoromethyl)furan (8.34 g, 54%).
