Procedure

To a solution of 1,1-dimethylethyl 4-[5-(2-chloro-4-pyrimidinyl)-4-(2-fluoro-3-{[(2-propen-1-yloxy)carbonyl]amino}phenyl)-1,3-thiazol-2-yl]-4-methyl-1-piperidinecarboxylate (670 mg, 1.139 mmol) in dichloromethane (8 mL) were added tributylstannane (332 mg, 1.139 mmol), tetrakis (65.8 mg, 0.057 mmol) and water (66 μl, 3.66 mmol). The reaction mixture was stirred for 1 h. The reaction mixture was concentrated and residue was purified using column chromatography (hexane/EtOAc, 0 to 100%) to obtain the title compound (482 mg). MS (ESI): 504.2 [M+1]+.
