在三氯氧磷存在下，以甲酰胺和邻氨基苯甲酸类化合物为原料，用改进的Niementowski反应合成了5种喹唑啉酮化合物：6-X-4(3H)-喹唑啉酮(X=NO2,Cl,Br,I)和1-(呋喃-2-甲基)-6-磺酰胺基-7-氯-4(1H)-喹唑啉酮，并对该反应的历程进行了初步探讨。

Five quinazolinone compounds, such as 6-X-4(3H)-quinazolinone(X=NO2, Cl, Br, I) and 1-furfuryl-6-sulfamide-7-chloro-4(1H)-quinazolinone, were synthesized by reaction of anthranilic acids with formamide in presence of phosphoryl chloride. The mechanism of this reaction was also studied.
