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.
标题化合物是通过将3-氨基-3,4-二氢-4-羟基-4-苯基喹唑啉与卤代乙酸衍生物反应制备的,将所得的卤代乙酰衍生物与弱酸反应,将所得的2-(3-卤甲基-s-三唑-4-基)苯并酮与羟胺反应,并将所得的2-(3-羟氨基甲基-s-三唑-4-基)苯并酮脱水以实现环闭合。
