METHOD OF PRODUCING AMINOPYRIDINE DIMER

摘要

PROBLEM TO BE SOLVED: To provide a method of synthesizing an aminopyridine dimer that can be used as a basic catalyst for acylation of an alcohol and provide a novel aminopyridine dimer. SOLUTION: The objective aminopyridine dimer are obtained by allowing a halogenated pyridine to react with a bipyrrolidine in the presence of an alkali at a pressure of >=0.6 GPa and at a temperature of >=65 deg.C.
