Abstract
A method has been developed for the synthesis of methyl piperazinium-2-carboxylate dihydrochloride (overall yield 46%) and piperazinium-2-carboxylic acid dihydrochloride (overall yield 36%), from ethylene diamine through N,N′-di(trifluoroacetyl) ethylenediamine and methyl N,N′-di(trifluoroacetyl)piperazine-2-carboxylate. The N,N′-dinitroso derivatives were synthesized.
