Abstract
The selective decarboxylation of 1-methyl-4,5-imidazoledicarboxylic acid was carried out in various solvents. 1-Methyl-5-imidazolecarboxylic acid was obtained by heating in acetic or propionic anhydride, whereas 1-methyl-4-imidazolecarboxylic acid was obtained in N,N′-dimethylformamide, N,N′-dimethylacetamide, or N-methylpyrrolidone or by pyrolysis. The reaction mechanism is discussed.
