以2-氨基噻吩-3-甲酸甲酯(3.0g,19.1mmol)和甲酰胺(95ml)为原料,在190℃下加热反应4小时,合成噻吩并[2,3-d]嘧啶-4(3H)-酮。反应完成后,将混合物冷却至室温,并倒入水中。通过过滤收集沉淀物,用水洗涤后干燥。粗产物通过硅胶柱色谱法(洗脱剂:CH2Cl2/MeOH = 50:1)进行纯化,得到目标化合物噻吩并[2,3-d]嘧啶-4(3H)-酮,为白色固体(1.93g,收率66%)。产物结构经1H NMR(300MHz,DMSO,25℃)和HRMS确认:1H NMR δ= 12.49(s,1H,NH),8.13(s,1H,CH),7.58(d,J = 5.8Hz,1H,CH),7.39(d,J = 5.8Hz,1H,CH)ppm;HRMS(计算值C6H5N2OS:153.01226,实测值:153.01155)。
