Procedure
To a solution of 1,1-dimethylethyl {1-[4-(3-amino-2-fluorophenyl)-5-(2-chloro-4-pyrimidinyl)-1,3-thiazol-2-yl]-1-methylethyl}carbamate (400 mg, 0.862 mmol) in pyridine (50 mL) was added dropwise 2,6-difluorobenzenesulfonyl chloride (238 mg, 1.121 mmol). After 4 h, 2,6-difluorobenzenesulfonyl chloride (0.20 g) was added to the reaction mixture and stirred at rt overnight. The reaction mixture was concentrated. The residue was purified via chromatography on silica gel to obtain the title compound (330 mg 59% yield). MS (ESI): 639.9 [M+H]+
