Following the method described by Hennessy and Buchwald in J. Am. Chem. Soc., 2003, 125, 12084-12085, 2-chloro-N-(2-fluoro-4-nitro-phenyl)-N-methyl-acetamide (15, 1.00 g, 4.05 mol), palladium acetate (27.3 mg, 0.122 mmol) and 2-(di-tert-butylphosphino)biphenyl (72.5 mg, 0.243 mmol) are placed under a nitrogen atmosphere, and toluene (20 ml) and triethylamine (0.85 ml, 6.08 mmol) are added via syringe. The reaction is heated at 80° C. for 4 hours and then evaporated to dryness. The dark residue is purified by PTLC (dichloromethane) to give the title compound as a light brownish-orange solid. HPLC r.t. 4.4 min.
