Versuchsvorschrift

Methyl 2-methoxy-5-(1H-tetrazol-5-yl)benzoate (0.78 g, 3.33 mmol) methyl iodide (0.21 mL, 3.33 mmol) and potassium carbonate (0.46 g, 3.33 mmol) were combined in acetone (8 mL) and heated at reflux overnight. After cooling to room temperature, the mixture was filtered and concentrated. Flash chromatography on silica gel afforded 170 mg (21%). LC/MS (HPLC method 3): tR=2.01 min, 249.09 (MH)+
