Versuchsvorschrift
To a solution of 3.3 g. (0.03 mole) of 3-amino-2-pyridone in 75 ml. of pyridine cooled in ice was added portionwise 6.3 g. (0.04 mole) of 2-fluorobenzoyl chloride over 5 minutes. After stirring for 15 hours at ambient temperature, the mixture was poured into ice-water. The resultant precipitate was collected by filtration, washed with water and recrystallized from ethanol to give 3-(2-fluorobenzoylamino)-2-pyridone, m.p. 223° C.
