1-Azido-2,3-dichlorobenzene (200 mg, 1.06 mmol) (Cambie J. Organomet. Chem. 1996, 507, 1) and 3-phenyl-1-propyne (150 μL, 1.1 equiv) were combined in toluene (0.2 mL) and heated at 100° C. for 18 hours, allowed to cool to room temperature, and then concentrated under reduced pressure to give a mixture of regioisomers. The residue was purified by flash chromatography eluting with hexanes:ethyl acetate (3:1) to provide the title compound.
