Abstract
5-Phenyl-9-bromotetrazolo[1, 5c]quinazoline (I) was synthesized. It was shown that I is covalently hydrated at the N(6)=C(5) bond. The structure of the covalent hydrate (V) was confirmed by cleavage to 5-(2′-amino-5′-bromophenyl) tetrazole. The probable mechanisms of the covalent hydration and cleavage are examined. V was converted to the 5-methyl derivative (VII).
