Versuchsvorschrift
Add sodium azide (2.44 g, 37.49 mmol) to crude 4-bromomethyl-2-chloro-benzoic acid methyl ester (7.6 g, 28.84 mmol) in anhydrous dimethylformamide (100 mL) at room temperature under argon gas. Stir the reaction mixture at 50° C. overnight. Quench the reaction mixture with water and extract with ether (3×). Combine the organic layers, wash with brine, dry over sodium sulfate, and concentrate to provide the crude product (5.8 g, 25.7 mmol).
