Procedure
To a solution of 1,1-dimethylethyl 4-[4-(3-amino-2-fluorophenyl)-5-(2-chloro-4-pyrimidinyl)-1,3-thiazol-2-yl]-1-piperidinecarboxylate (300 mg, 0.612 mmol) in pyridine (3 mL) was added 3-furansulfonyl chloride (153 mg, 0.918 mmol, and the reaction mixture was stirred for 3 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 give 310 mg of the title compound. MS (ESI): 620.2, 622.2 [M+1]+.
