4,5,6,7,8-hexahydro[1]benzothieno[2,3-d]pyrimidine-7-carbonitrile which was treated with phosphoryl chloride to obtain the corresponding 4-chloro derivative. Reactions of the latter with secondary amines afforded a series of 4-aminobenzothienopyrimidines, and the reaction with hydrazine hydrate, followed by cyclization with formic acid, furnished 9-phenyl-8,9,10,11-tetrahydro[1]benzothieno[3,2-e][1
摘要 2-氨基-6-氰基-6-苯基-4,5,6,7-四氢-1-苯并噻吩-3-羧酸乙酯与甲酰胺缩合得到4-氧代-7-苯基-3,4,5, 6,7,8-六氢[1]苯并噻吩并[2,3 - d ]嘧啶-7-甲腈经磷酰氯处理得到相应的4-氯衍生物。后者与仲胺反应得到一系列 4-氨基苯并噻吩并嘧啶,与水合肼反应,然后与甲酸环化,得到 9-苯基-8,9,10,11-四氢[1]苯并噻吩[3, 2- e ][1,2,4]三唑并[1,5 - c ]嘧啶-9-甲腈。
