実験手順
To a mixture of 2.80 g (20 mmol) of 3-hydroxypicolinic acid, 4.13 g (25 mmol) of n-hexyl bromide and 30 ml of N,N,-dimethylformamide was added 2.8 g (0.02 mmol) of anhydrous potassium carbonate, and the mixture was stirred under heating at 100° C. for 4.5 hours. After cooling, 60 ml of ice-water was added, and the mixture extracted with ethyl acetate. The solution was subjected to evaporation under a reduced pressure and the residue separated by silica gel column chromatography (ethyl acetate:hexane=3:7), to obtain 2.60 g of a colorless oily substance (yield 40.5%).
