2,5-dimethoxytetrahydrofuran, gave 1-[3-(thienyl-2-aminomethyl)]pyrrole. This compound was found to be a convenient intermediate for the preparation of 4-aryl-5,6-dihydro-4H-pyrrolo[1,2-a]thieno-[2,3-f][1,4]diazepines which was accomplished by two different synthetic routes.
3-氨基噻吩-2-腈与2,5-二甲氧基四氢呋喃缩合形成的1- [3-(噻吩-2-甲腈)]吡咯的还原,得到1- [3-(噻吩-2-氨基甲基)]吡咯。发现该化合物是制备4-芳基-5,6-二氢-4 H-吡咯并[1,2- a ]噻吩并-[2,3- f ] [1,4]二氮杂pine的方便中间体。是通过两种不同的合成途径完成的。
