Abstract
It has been shown that when there is no substituent in position 5 of a tetrazolo[1, 5-c]quinazoline covalent hydration at the N(6)=C(5) bond and cleavage of the pyrimidine ring with the formation of 5-(2′-aminophenyl)-tetrazole take place more readily than in the case of the 5-methyl derivative. The 5-phenyl derivative of tetiazolo[1, 5-c]quinazoline does not undergo hydration. The mechanism of the hydration of the compounds mentioned is discussed.
