Reaction Steps
In 20 ml of N,N-diimethylformamide were dissolved 1.0 g of 5-chloro-6-hydroxynicotinic acid. To the resulting solution were added 4.78 g of potassium carbonate and 1.26 ml of 2-iodopropane, followed by stirring under heat at 8° C. for 4 hours. Ice water was added to the reaction mixture and the resulting mixture was extracted with ethyl acetate. The organic layer was successively washed with water and saturated saline, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue so obtained was subjected to chromatography on a silica gel column (developing solvent: 5% ethyl acetate/n-hexane), whereby 600 mg of the title compound were obtained.
