반응 단계
Nitrogen was bubbled through a solution of 2,4-dichloropyrimidine (1 eq) in tetrahydrofuran and water (3:1) for 0.5 h. Bis(diphenylphosphino)ferrocene Palladium(II)chloride (0.05 eq) followed by pyridine-3-boronic acid (1 eq) and sodium carbonate (3 eq) was added and the mixture was heated to 60° C. for 16 h under nitrogen. The reaction mixture was concentrated and partitioned between ethyl acetate and water. The organic layer was washed with brine and dried with sodium sulfate and concentrated. Purification on silica gel gave 2-chloro-4-(3-pyridyl)pyrimidine. MS: MH+=190.
