Procedure

A mixture of 23.9 g of 2-chloro-5-iodopyridine, 14 ml of thiobenzoic acid, 1.90 g of copper iodide, 3.60 g of 1,10-phenanthroline, 35 ml of diisopropylethylamine and 200 ml of toluene was stirred at 110° C. for 4 hours. Water was added to the reaction mixture cooled to room temperature, and the insoluble matter was filtered with celite (registered trademark), then the filtered matter was washed with ethyl acetate, and the filtrate was extracted with ethyl acetate. The combined organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The resulting residue was applied to a silica gel column chromatography to obtain 21.2 g of thiobenzoic acid S-(6-chloropyridin-3-yl)ester.
