Abstract：The unsymmetrically 4-methyl-2,2′-bipyridines were synthesized from two material. The one was 2-bromine-pyridine and the other was 4-methyl-pyridine, which reacted with bromized-pyridine to get the title compoudns using Pd(O) as catalyst. The structure of the compound was proved by NMR and IR.

Key words：4-methyl-pyridine; Stille reaction; 4-methyl-2; 2′-bipyridine; charge
