Compound Q&A
How is 2'-{[5-(4-Methyl-1-piperazinyl)-2-pyridinyl]amino}-7',8'-dihydro-6'H-spiro[cyclohexane-1,9'-pyrazino[1',2':1,5]pyrrolo[2,3-d]pyrimidin]-6'-one dihydrochloride (CAS: 1977495-97-8) typically synthesized?
Answer
![2'-{[5-(4-Methyl-1-piperazinyl)-2-pyridinyl]amino}-7',8'-dihydro-6'H-spiro[cyclohexane-1,9'-pyrazino[1',2':1,5]pyrrolo[2,3-d]pyrimidin]-6'-one dihydrochloride](https://static.chemtradehub.com/structs/197/1977495-97-8-c7e6.webp "2'-{[5-(4-Methyl-1-piperazinyl)-2-pyridinyl]amino}-7',8'-dihydro-6'H-spiro[cyclohexane-1,9'-pyrazino[1',2':1,5]pyrrolo[2,3-d]pyrimidin]-6'-one dihydrochloride")
The compound is typically synthesized via a multi-step process involving the coupling of a pyridine derivative with a piperazine derivative in the presence of a base. The reaction yields a dihydrochloride salt, which is then purified by recrystallization. The reaction is highly selective and provides good yield.
