Procedure

In a 5 ml glass tube were placed 5-bromo-thiophene-2-carboxylic acid [1-(3,5-difluoro-4-methanesulfonylamino-phenyl)-ethyl]-amide (50 mg, 0.14 mmol), 3-isopropylphenol (62 mg, 0.27 mmol), CuI (5 mg, weight of 10%), Cs2CO3 (88 mg, 0.27 mmol), NMP (1 mL), ethanol (1 mL), and a magnetic stir bar. The vial was sealed with septum and placed into the Microwave cavity. The vial was irradiated in a Microwave synthesizer at 195° C. for 120 min. The mixture was diluted with EtOAc and washed with 1N HCl and water. The organic layer was dried over anhydrous MgSO4 and concentrated under reduced pressure. The crude residue was purified by column chromatography (gradient 12% to 100% EtOAc in n-hexane) to give title compound (2.5 mg, 4.5%).
