Versuchsvorschrift

This reaction was carried out as described in Example 40, step c, using 5-(3-bromophenyl)-1H-[1,2,4]triazole (1.60 g, 7.2 mmol), K2CO3 (2.47 g, 17.8 mmol) and MeI (667 μl, 10.7 mmol). The residue was purified by column chromatography (silica gel, 80% Et2O/isohexane) to yield first 5-(3-bromophenyl)-1-methyl-1H-[1,2,4]triazole (190 mg, 11%), and then the solvent polarity was increased to 100% EtOAc to yield 3-(3-bromophenyl)-1-methyl-1H-[1,2,4]triazole (935 mg, 55%).
