Procedure

To a solution of 1,1-dimethylethyl 4-[4-(3-amino-2-fluorophenyl)-5-(2-chloro-4-pyrimidinyl)-1,3-thiazol-2-yl]-4-methyl-1-piperidinecarboxylate (200 mg, 0.397 mmol) in pyridine (2 mL) was added 2,6-difluorobenzenesulfonyl chloride (130 mg, 0.612 mmol) and the reaction mixture was stirred for 5 h. The reaction mixture was quenched with water (5 mL) and extracted with EtOAc (3×). The extract was dried, filtered and concentrated. The residue was purified using column chromatography (40 to 100% EtOAc/hexane) to obtain the title compound (220 mg). MS (ESI): 680.4 [M+1]+.
