Procedure

3,5-Bis(trifluoromethyl)phenylboronic acid (67.1 mg, 0.26 mmol) and 2-chloro-thiazole-4-carboxylic acid [1-(3,5-difluoro-4-methanesulfonylaminophenyl)-ethyl]-amide (50 mg, 0.13 mmol) was reacted using Pd(PPh3)2Cl2 (7 mg, 0.01 mmol), Cs2CO3 (127 mg, 0.39 mmol) as described above to give the title compound (21 mg, 28%) after purification by flash chromatography on silica gel (hexane: EtOAc=1:1).
