PROCESS FOR PREPARING 2,6-BIS(AMINO PHENOXY) PYRIDINE

摘要

A 2,6-bis-(3- or 4-aminophenoxy) pyridine of formula (I) is prepd. by either reacting 216-dihalogenopyridine with 3- or 4-aminophenol in the presence of a base in polar aprotic solvents, or reacting 2,6- dihalogenopyridine with 3- or 4-nitrophenoe), and thus reducing a resultant 2,6-bis-(3-or 4-nitrophenoxy) pyridine. A 2,6- bis-(3- or 4-aminophenoxy) pyridine is useful as a starting material for preparing polyimide resins having good processabilities and adherent strengths.
