A simple and practical method for the synthesis of 1-alkyl-5-methyl ester-1H-1,2,3-triazole-5-carboxylate from low boiling point azides is demonstrated. The triazoles were constructed by 1,3-dipolar cycloaddition of methyl 3-(trimethylsilyl) propiolate with alkyl azides containing one to four carbons. To better handle the volatility of the alkyl azides, a flow chemistry method was developed to ensure
