Procedure

To a solution of 1,1-dimethylethyl 4-[4-(3-{[(2,6-difluorophenyl)sulfonyl]amino}-2-fluorophenyl)-5-(2-methyl-4-pyrimidinyl)-1,3-thiazol-2-yl]-1-piperidinecarboxylate (60 mg, 0.093 mmol) in dichloromethane (DCM) (2 mL) was added TFA (0.5 μL, 6.49 μmol), and the reaction mixture was stirred for 1 h. The reaction mixture was concentrated and the residue was purified using RP-HPLC. The TFA salt was neutralized to give 32 mg of title compound. MS (ESI): 546.1 [M+1]+.
