A high-yield synthesis was developed for the preparation of 2,2'-bipyrimidine (1) using the Ullmann coupling of 2-iodopyrimidine. The new procedure was also used for the preparation of 4,4',6,6'-tetramethyl-2,2'-bipyrimidine (2) and 5,5'-dibromo-2,2'-bipyrimidine (3).
利用2-碘嘧啶的Ullmann偶联,开发了用于制备2,2'-联嘧啶(1)的高产率合成。该新方法还用于制备4,4',6,6'-四甲基-2,2'-联嘧啶(2)和5,5'-二溴-2,2'-联嘧啶(3)。
