0.25 g (1.31 mM) of copper(I) iodide, 7.26 g (52.5 mM) of potassium carbonate and 5.8 g (26.25 mM) of 6-iodo-3-pyridinol are introduced into a tube under an argon atmosphere. 30 ml of isopropanol, 5 g of 1,2-dimethoxyethane and 3.55 g (26.25 mM) of 4-mercaptobenzonitrile are then added. The tube is sealed and heated at 80° C. for 24 hours. When the mixture has returned to room temperature, it is diluted with 120 ml of ethyl acetate and filtered, the solid on the filter is washed with ethyl acetate and the organic phases are concentrated under reduced pressure. The evaporation residue is purified by chromatography on a silica column (eluent: cyclohexanol/ethyl acetate 55/45; v/v) to give the expected product in the form of a beige powder with a yield of 53%.
