Procedure
To 50 ml of dimethylformamide are added 5 g of 2-(4-hydroxyphenoxy)-3-(2-thenoyl)pyridine, 3.5 g of potassium carbonate and 0.5 g of potassium iodide, and the mixture is stirred at room temperature for 30 minutes. Thereto is added 4.1 g of 6-dimethylaminohexyl chloride. The mixture is stirred at 50° C. for 7 hours. Then, the mixture is poured into ice-water, followed by addition of ethyl acetate thereto. The ethyl acetate layer is extracted with hydrochloric acid and the extract is rendered alkaline with potassium carbonate. The isolated oily substance is extracted with ethyl acetate. The extract is washed with water and dried over anhydrous magnesium sulfate. Thereafter, the solvent is distilled off. The residue is converted into the salt with fumaric acid in ethanol. The salt is recrystallized from ethanol to give 2-[4-(6-dimethylaminohexyloxy)phenoxy]-3-(2-thenoyl)pyridine fumarate, m.p. 98°-101° C.
