Reaction Steps

A mixture of 5-iodo-4-methyl-3-nitro-2-pyridone (8.0 g. 28.6 mmol) and sodium hydride (1.03 g, 43 mmol) in DMF (150 mL) was stirred at rt for 1 hour. n-Hexyl bromide (8.03 mL, 57.2 mmol) was added, and the mixture was stirred for 24 hours. Water was added, and the mixture was extracted with ethyl acetate. The organic phase was washed, dried, filtered and evaporated. Chromatography of a portion of the residue over silica gel (20% petroleum ether/methylene chloride) gave 1-hexyl-5-iodo-4-methyl-3-nitro-2-pyridone.
