The title compounds are prepared by reacting a 3-amino-3,4-dihydro-4-hydroxy-4-phenylquinazoline with a reactive derivative of a halogenoacetic acid, reacting the resultant halogenoacetyl derivative with a weak acid, reacting the resultant 2-(3-halomethyl-s-triazol-4-yl)benzophenone with hydroxylamine and subjecting the resultant 2-(3-hydroxyamino-methyl-s-triazol-4-yl)benzophenone to dehydration to effect ring closure.
