Procedure
A solution of tosyl azide (16) (1.0 equiv) in CHCl3 (0.5M) cooled to 0° C. was treated with 2-chlorophenyl acetylene (15) (1.2 equiv), 2,6-lutidine (1.2 equiv) and CuI (0.1 equiv). The resulting mixture was stirred at 0° C. for 24 h, quenched with 10% HCl, the layers separated and the aqueous one washed with brine, dried (MgSO4), filtered and concentrated in vacuo. The residue was purified by flash chromatography (Hexane/AcOEt 5:1, 3:1 and 1:1) to provide 4-(2-chlorophenyl)-1-tosyl-1H-1,2,3-triazole (17) as a pale yellow crystalline solid.
