A 30 mL scintillation vial was charged with 2-azido-4-chloro-1-nitrobenzene (200 mg, 1.0 mmol) and 0.75 M 3-methyl-1-butynylmagnesium chloride in THF (1.6 mL, 1.2 mmol; prepared by mixing 3-methyl-1-butyne (120 μL, 1.2 mmol) and iPrMgCl (1.5 mL, 1.0 M in THF) at room temperature, heating to 40° C. for 30 minutes then cooling to room temperature). The reaction was allowed to stir at room temperature for 1 hour after which the reaction was quenched with SiO2 and the solvent removed. The product (adsorbed to SiO2) was then loaded on a SiO2 column and purified to give 1-(5-chloro-2-nitro-phenyl)-5-isopropyl-1H-[1,2,3]triazole.
