実験手順

To a solution of N-(5-Chloro-1,3-thiazol-2-yl)-3-cyano-4-fluorobenzenesulfonamide (Preparation 52, 100 mg, 0.32 mmol) and potassium carbonate (109 mg, 0.8 mmol) in dimethylformamide (3 ml) was added 4-fluoro-2-iodophenol (Preparation 218, 0.32 mmol) and the reaction heated at 80° C. for 24 hours. The solution was added dropwise into rapidly stirring hydrochloric acid (2M aqueous solution). The fine dark precipitate was filtered and dried in vacuo to afford the title product as a brown solid, 100 mg, 59% yield.
