A suspension of cesium carbonate (1.11 g, 3.41 mmol), 5-[1-(4-chloro-benzyl)-1H-[1,2,3]triazol-4-yl]-2-methyl-phenol (0.75 g, 2.50 mmol) (from Example 34 supra) in tetrahydrofuran-N,N-dimethylformamide (5:2, 23 mL) was heated at 70° C. for 2 hours. 3-Bromomethyl-4-chloro-thieno[3,2-c]pyridine-7-carboxylic acid ethyl ester (0.76 g, 2.27 mmol) (from Example 1 supra) was added. Heating was continued for 18 hours. The reaction mixture was partitioned between ethyl acetate and water. The precipitate was filtered, washed with ethyl acetate and dried to give 4-chloro-3-{5-[1-(4-chloro-benzyl)-1H-[1,2,3]triazol-4-yl]-2-methyl-phenoxymethyl}-thieno[3,2-c]pyridine-7-carboxylic acid ethyl ester as a white powder. (Yield 0.33 g, 26%).
