Reaction Steps

3-Hydroxy-5-methoxycarbonylpyridine (1.68 g, prepared using the method described in Bull. Acad. Sci. (Chem. Div.), (1976), 598) and 2-bromobromo-N-(5-methylhex-3-yn-5-yl)-butyramide (3.06 g) were dissolved in dry N,N-dimethylformamide (30 ml) containing anhydrous potassium carbonate (2.35 g). The mixture was heated to 70° C. for 3 hours with stirring, cooled to ambient temperature, diluted with water and extracted with diethyl ether (three times). The organic extracts were combined, washed with water (three times), dried over magnesium sulphate and evaporated under reduced pressure to give a brown gum. The gum was fractionated by chromatography (silica; diethyl ether) to give the required product, 2.38 g, as a yellow oil.
