The 5-decyl-1H-tetrazole, (4.0 g, 0.019 mol), triethylamine (2.9 mL, 0.021 mol) and ethyl 2-bromophenylacetate (5.09 g, 0.021 mol) were dissolved in 200 mL acetonitrile and heated to reflux for 2 hours. Cooled and concentrated in vacuo to give a yellow oil. Chromatography to separate the regioisomers gave ethyl (±)-5-decyl-α-phenyl-2H-tetrazole-2-acetate as a clear oil (2.40 g, 34%).
