✦ Synopsis

Hydrazonoyl halides 4 react readily with either 3-amino-2,3-dihydro-6-methyl-2-thioxo-4(1H)-pyrimidinone 5 or 3-amino-6-methyl-2-methylthio-4(3H)-pyrimidinone 6 to form 6H-pyrimido [1,2-b][1,2,4,5]tetrazin-6-ones 9. The mechanism of the studied reactions is discussed.

Several new pyrimido[ 1,2-albenzimidazole derivatives were synthesized by reacting 2-aminobenzimidazole with u, p-unsaturated nitriles and benzoylacetonitrile derivatives. The structures of the products were established on the basis of elemental analyses, IR and 'H-NMR spectral data. ## Umsetzungen
