Procedure
To a solution of 2,6-dibromopyridine. (1.0 eq.) in DMSO (0.3M) was added sodium methylsulfide (1.1 eq.). The mixture was stirred for 2 d at rt then poured in water. The resulting precipitate was filtered off and the filtrate was extracted with Et2O (2×). The combined organic extracts were washed with brine, dried over MgSO4, filtered and concentrated to afford the title compound as a colorless oil.
