Reaction Steps

Prepared from 3-[1,2,3]triazol-1-yl-benzoic acid [prepared by refluxing of methyl 3-azidobenzoate [CAS-No. 93066-93-4] in trimethylsilylacetylene, followed by saponification with aqueous NaOH in refluxing EtOH] by activation with ethyl chloroformate/Et3N and reaction with ethyl malonate potassium salt with Et3N and MgCl2 in CH3CN according to general procedure H (method a). Obtained as a light yellow solid (2.22 g).
