Quinazolin-4(3H)-ones(1) were conveniently synthesized from anthranilic acids and amidines,which could be chloridized with POCl_3 to obtain 4-chloroquinazolines (2).The reaction of 2 and 1H-pyrazol-3-amine would give two types of products.In the presence of acid or base,the C-N bond would be formed between the 4-position carbon of 2 and the NH_2 of 1H-pyrazol-3-amine.While the C-N bond between the 4-position carbon of 2 and the NH of 1H-pyrazol-3-amine would be formed when Pd catalyst was utilized.

以邻氨基苯甲酸类化合物和脒为原料，可方便地获得喹唑啉-4(3H)-酮类产物(1)，1经POCl_3氯化可到4-氯代喹唑啉化合物(2)。2与3-氨基-1H-吡唑化合物反应可得到两种类型的产物，在酸、碱条件下2的4位碳和3-氨基-1H-吡唑化合物的NH_2发生C-N成键反应；在Pd催化条件下，2的4位碳则和3-氨基-1H-吡唑化合物的环内NH发生C-N成键反应。
