- Synthesis of 1,2-Di-(4-pyridyl)ethylenediamine and Related Compounds
-
Hydrolysis of N,N'-diacyl-1,2-di(4-pyridyl)ethylenediamines 1 in aqueous sulfuric acid gave the corresponding imidazolines 3. 1,2-Di-(4-pyridyl)ethylene diamine 2 was prepared in 61percent yield by treating N,N'-di-t-butyloxycarbonyl-1,2-di(4-pyridyl)ethylenediamine 4 with trifluoroacetic acid or in 94percent yield by the hydrolysis under basic conditions of N,N'-diphthaloylglycyl-1,2-di(4-pyridyl)ethylenediamine 13.
