実験手順

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, 0.12 mmol), 3-isopropyl phenyl boronic acid (37 mg, 0.23 mmol), Cs2CO3 (114 mg, 0.34 mmol), Pd(PPh3)2Cl2 (6.4 mg, 0.009 mmol), DME (0.8 mL), ethanol (0.2 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 140° C. for 20 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 (42 mg, 77%).
