Potassium Carbonate → 1-(3-fluoro-4-nitro-phenyl)-1H-pyridin-2-one

Participants

Reaction Steps

2.5 g (26.3 mmol) 2-hydroxypyridine, 2.9 ml (26.3 mmol) 2,4-difluoronitrobenzene, are dissolved in 100 ml acetone, combined with 4.0 g (28.9 mmol) potassium carbonate and stirred for one day at ambient temperature. The undissolved matter is filtered off and the salt residues are rinsed with acetone. The combined organic phases are evaporated to dryness. The residue is purified by chromatography (silica gel; eluant: cyclohexane-ethyl acetate gradient).
