Versuchsvorschrift
0.8 g of 4-trifluoromethyl-3-pyridine carboxamide was dissolved in 7 ml of acetic acid. Then, 0.72 g of a 30% hydrogen peroxide aqueous solution was gradually dropwise added thereto. After completion of the dropwise addition, the reaction solution was heated to 70° C. and stirred for 8 hours at this temperature. After completion of the reaction, the solvent was distilled off under reduced pressure. The residue thereby obtained was washed with n-hexane to obtain 0.6 g of 4-trifluoromethyl-3-pyridine carboxamide 1-oxide (melting point: 198.8° C.) as the desired product.
