Versuchsvorschrift

0.4 g of 5-trifluoromethyl-2-pyridone was dissolved in 10 ml of acetic acid, and 0.4 g of bromine was added to the solution which was subsequently reacted for 4 hours while stirring. After completion of the reaction, the acetic acid was distilled off, and recrystallization was carried out from a mixed solvent of methylene chloride and n-hexane to obtain 0.45 g of the titled compound having a melting point of 162° to 165° C.
