Compounds 2 and 4 reacted with nitrous acid to give tetrazolothienopyrimidine 5 and 7, respectively, which was reduced to aminothienopyrimidone 6 and 8, respectively. Also, reaction 2 and 4 with aliphatic acid gave thienotriazolopyrimidine 9 and 10, respectively. On the other hand, 2-hydrazino derivative 2 and 4-hydrazino derivative 4 reacted with α-haloketone to yield thienopyrimidotriazine 14 and
化合物 2 和 4 与亚硝酸反应,分别得到四唑并噻吩并嘧啶 5 和 7,分别还原为氨基噻吩并嘧啶酮 6 和 8。此外,与脂肪酸的反应 2 和 4 分别得到噻吩并三唑并嘧啶 9 和 10。另一方面,2-肼基衍生物2和4-肼基衍生物4分别与α-卤代酮反应生成噻吩并嘧啶并三嗪14和15,与β-二酮和β-酮酯反应生成吡唑基衍生物16-21。吡唑啉酮衍生物 20 和 21 与芳香醛缩合,分别得到亚芳基衍生物 22 和 23。
