Vorschrift

To a hot mixture of 1-Iodo-4-isopropyl-2-methoxy-5-(toluene-4-sulfonyl)-benzene (0.5 g, 1.12 mmol), CuI, KF in anhydrous DMF (10 ml) at 120° C. oil bath temperature, was added trifluoromethyl iodide (0.64 g, 4.48 mmol) in portions over 30 min. The reaction mixture was heated for 4 hrs and poured into H2O (100 ml). The insoluble solid, which was collected by filtration was triturated with methylene chloride, filtered and concentrated to give 1-Isopropyl-5-methoxy-2-(toluene-4-sulfonyl)-4-trifluoromethyl-benzene (0.45 g, 100%) as a solid.
