Synthesis of Zaleplon

Huang Xuefeng, Li Yuyan, You Qidong (Dept. of Medicinal Chemistry, China Pharmaceutical University, Nanjing 210009, P. R. China)  
Objective: To research the synthesis technique of zaleplon. Method:Zaleplon was prepared from acetophenone by nitrating, reducting, acetylating, condensation with dimethy formide dimethylacetal, alkylation with ethyl iodide and cyclization with 3-aminopyrazole-4-carbonitrile,ets. Conclusion; This synthetic route is reasonable, the total yields of zaleplon was 3.2% .
