To a solution of 18.7 g (0.17 mol) of 6-hydroxy-2-methylpyridine (commercially available) and 24.0 g (0.17 mol) of n-butyl bromide dissolved in 100 ml of dimethylformamide was added 23.0 g (0.17 mol) of potassium carbonate, and the mixture was stirred at 90°-110° C. for 8 hours. To the mixture was added 300 ml of ice-water, and the mixture extracted with ethyl acetate, followed by a separation of the oily extract obtained by silica gel chromatography (ethyl acetate:hexane=7:97) to give 19.8 g of an oily substance (yield 69.9%).
