実験手順
A mixture of 1.50 g (4.66 mmol) of 3-benzyloxy-6-bromo-2-nitrotoluene, 6.33 g (46.6 mmol) of sodium trifluoroacetate, 4.43 g (23.3 mmol) of copper (I) iodide and 80 ml of N-methylpyrrolidone was heated at 160° C. for 7 hours while stirring. Next, the solvent was distilled off under reduced pressure and ethyl acetate was added to the resulting residue. Insoluble matters were then filtered off. The filtrate was washed twice with water. After drying over anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure and the residue was isolated and purified by silica gel column chromatography to give 0.70 (48.3%) of 3-benzyloxy-6-trifluoromethyl-2-nitrotoluene.
