摘要：Noval diamines, 2,6-bis(3-aminophenoxy)pyridine and 2,6-bis-(4-aminophenoxy)pyridine, are provided and the method of their preparation is disclosed.These diamines are useful as raw materials for polyimide.

These diamines can be prepared by the reaction of 2,6- dichloropyridine or 2,6-dibromopyridine with 3-aminophenol or 4- aminophenol in aprotic polar solvents in thepresence of bases.

Besides, 2,6-bis(3-aminophenoxy)pyridine can also be prepared by the reaction of 2,6-dicholorpyridine or 2,6-dibromopyridine with 3- nitrophenol, followed by reducingresultant 2,6-bis(3-nitrophenoxy) pyridine.
