참여 물질

반응 단계

1.0 g of N-[4-(trifluoromethyl)phenyl]-2-(2-methoxyphenyl)acetamide was dissolved in 10 mg trifluoroacetic acid, and 0.46 g hexamethylene tetramine was added, and the mixture was reacted at 85° C. for 3 hours. The reaction solution was returned to room temperature, water and ethyl acetate were added, and sodium bicarbonate was further added until the pH reached 8. The reaction solution was extracted with ethyl acetate, washed with brine and dried over anhdydrous magnesium sulfate and the solvent was evaporated. The residue was subjected to silica gel column chromatography, to give 0.7 g of N-[4-(trifluoromethyl)phenyl]-2-(5-formyl-2-methoxyphenyl)acetamide as a colorless oil from fractions eluted with hexane-ethyl acetate (1:1).
