Tetrazole compounds. 8. Synthesis of tetrazolylpyrimidines from tetrazolyl-substituted enamino ketones
Fischer
, p. 1517 - 1520 (2007/10/02)
Tetrazolyl-substituted enamino ketones 1 react with various amidines 2 to give 5-(1-phenyl-1H-tetrazol-5-yl)pyrimidines 3. In the case of the chloroacetyl enamine 4 4-(N,N-dimethylaminomethyl)-substituted tetrazolylpyrimidines 5 were obtained. Subsequent
