2,4,6-Trichloro-5-methylpyrimidine (2.0 g, 10.13 mmol) and bis(triphenylphosphine)palladium chloride (0.142 g, 0.20 mmol) in DMF (40 mL) was degased. Tributyl(1-ethoxyvinyl)stannane (3.59 mL, 10.64 mmol) was added. The mixture was heated at 100° C. for 1.5 h under nitrogen atmosphere. The mixture was poured into a solution of KF (6 g) in water (100 mL). MTBE (100 mL) was added mixture was for stirred 10 min. The solid was removed by filtration and was washed with MTBE (60 mL). The organic phase was washed with water, dried over sodium sulfate and evaporated. The mixture was purified by column chromatography eluting with DCM to give the title compound as a solid, 1.15 g (49%).
