Abstract:p-Nitrobenzyl-2-diazoacetoacetate was synthesized by p-Nitrobenzyl acetoacetate and azide sodium in the presence of methyl sulfonylchloride. The main intermediate of p-Nitrobenzyl acetoacetate was synthesized by transesterification reaction with methyl acetoacetate and 4-nitrobenzyl alcohol. The overall yield obtained was 92.6 %.
Key words:p-nitrobenzyl-2-diazoacetoacetate;p-nitrobenzyl acetoacetate;synthesis
