Procedure
1,1-dimethylethyl 4-[5-(2-chloro-4-pyrimidinyl)-4-(3-{[(2,6-difluorophenyl)sulfonyl]amino}-2-fluorophenyl)-1,3-thiazol-2-yl]-4-methyl-1-piperidinecarboxylate (150 mg, 0.221 mmol) was dissolved into 1,4-dioxane (3 mL) and the solution was degassed for 10 min. PdCl2(dppf)-CH2Cl2 adduct (9.00 mg, 0.011 mmol) and dimethylzinc (0.221 mL, 0.441 mmol) were then added. The reaction mixture was stirred at 80° C. for 1 h. The reaction mixture was quenched with methanol (3 mL) and water (10 mL) and extracted with EtOAc (3×). The extract was dried over Na2SO4, filtered, and concentrated. The residue was purified using column chromatography (40% to 100% EtOAc/hexane) to obtain the title compound (75 mg). MS (ESI): 660.5 [M+1]+.
