Reaction Steps

A mixture of 1-azido-4-nitrobenzene (0.5 g, 3.0 mmol), propargyl bromide (80% in toluene) (0.7 mL, 0.6 mmol) and toluene (3 mL) in a sealed tube was heated to 60° C. for 24 h. The reaction mixture was cooled to room temperature and concentrated to give two inseparable isomers 4-(4-(bromomethyl)-1H-1,2,3-triazol-1-yl)aniline and 4-(5-(bromomethyl)-1H-1,2,3-triazol-1-yl)aniline in a 2/1 ratio (as judged by analytical HPLC analysis) which were hydrogenated to afford a mixture of 4-(4-methyl-1H-1,2,3-triazol-1-yl)aniline and 4-(5-methyl-1H-1,2,3-triazol-1-yl)aniline.
