The title ester 1 reacted with hydrazine hydrate to give hydrazide 2, which underwent intramolecular cyclization to yield 1-amino-7-phenyl-1H-imidazo[1,2-a]pyrimidine-2,5-dione (3) or took place in a substitution reaction with benzylamine to form N-benzyl-2-(2-benzylamino-4-oxo-6-phenyl-4H-pyrimidin-3-yl)-acetamide (4). The reaction of ester 1 with benzylamine gave corresponding amide 7, disubstituted
标题酯1与水合肼反应生成酰肼2,将其进行分子内环化,生成1-氨基-7-苯基-1H-咪唑并[1,2 - a ]嘧啶-2,5-二酮(3)或发生在与苄胺进行取代反应,以形成ñ -苄基2-(2-苄基氨基-4-氧代-6-苯基-4- ħ -嘧啶-3-基) -乙酰胺(4)。酯1与苄胺的反应得到相应的酰胺7,二取代衍生物4或1-苄基-7-苯基-1H-咪唑并[1,2 - a ]嘧啶-2,5-二酮(8),具体取决于反应条件。
