Procedure

2-(3,5-Dicyclopropyl-phenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (74 mg, 0.26 mmol) and 5-bromo-furan-2-carboxylic acid [1-(3,5-difluoro-4-methanesulfonylamino-phenyl)-ethyl]-amide (110 mg, 0.26 mmol) was reacted using Pd(PPh3)2Cl2 (14 mg, 0.02 mmol), Cs2CO3 (254 mg, 0.78 mmol) as described above to give the title compound (50 mg, 38%) after purification by flash chromatography on silica gel (% EtOAc in hexane=30%˜70%).
