Procedure

5-Hydroxy-2-iodo-benzonitrile (200 mg, 0.82 mmol) and PdCl2(PPh3)2 (20 mg, 0.028 mmol) and 2-furyltributyltin (400 g, 1.12 mmol) in N,N-dimethylformamide (5 mL) is degassed and heated at 100° C. for 15 min. After the mixture cooled to room temperature, an aqueous work up is performed and the product is isolated from chromatography (100 mg, 66%). MS (ESI): 184 (M−1)−1.
