Reaction Conditions

Reaction Steps

0.80 g of 2-hydroxy-4-(trifluoromethyl)benzaldehyde was dissolved in 8 ml dimethylformamide, and 0.78 g of ethyl iodide and 0.69 g of potassium carbonate were added, and the mixture was stirred at 70° C. for 2 hours. The reaction solution was diluted with water and then extracted with ethyl acetate. The organic layer was successively washed with 1N hydrochloric acid and brine, dried over anhydrous magnesium sulfate and the solvent was evaporated. The residue was subjected to silica gel column chromatography, and from fractions eluted with hexane-ethyl acetate (5:1), 0.60 g of 2-ethoxy-4-(trifluoromethyl)benzaldehyde was obtained.
