実験手順

3,4,5-Trimethoxyaniline (1.83 g; 10 mmol) is added to a 100 mL flask containing water (20 mL) and HCl (conc. aqueous solution, 5 mL). The solution is chilled to 0° C. and a solution of sodium nitrite (830 mg; 12 mmol) in water (5 mL) is added. The solution is stirred at 0° C. for 30 minutes, and then a solution of sodium azide (1.3 g; 20 mmol) in water (5 mL) is added. After another 30 minutes of stirring, dichloromethane is added (20 mL) and the organic phase was collected and filtered through a plug of silica, dried over magnesium sulfate and the solvent was evaporated to give approximately two grams of 3,4,5-trimethoxyphenyl azide.
