Reaction Steps
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]-1-piperidinecarboxylate (855 mg, 1.489 mmol) was dissolved into dichloromethane (DCM) (8 mL). To this solution were added tributylstannane (433 mg, 1.489 mmol), tetrakis (86 mg, 0.074 mmol) and water (0.083 mL, 4.62 mmol), and the reaction mixture was stirred for 1 h and concentrated. The residue was purified using column chromatography (0 to 100% EtOAc/hexane) to give 690 mg of the title compound. MS (ESI): 490.1 [M+1]+.
