To a stirred solution of 5-trimethylsilylethynyl-4-methyl-3-nitro-2-pyridone (1.0 g, 2.7 mmol) in THF (10 mL) was added tetrabutylammoniun fluoride (1M in THF, 2 mL). After 30 minutes the mixture was diluted with ethyl acetate, washed with water, dried, filtered and evaporated. Chromatography of the residue over silica gel (40% ethyl acetate/hexane) gave 5-ethynyl-4-methyl-3-nitro-2-pyridone (0.18 g, 22%).
