실험 절차

Diphenylphosphoryl azide (0.316 ml, 0.4 g, 1.46 ml, 1.1 eq) and 1,8-Diazabicyclo(5.4.0)undec-7-ene (0.219 ml, 0.22 g, 1.46 mmol, 1.1 eq) were added to a stirred solution of (3-methoxy-5-nitrophenyl)methanol in 10 ml anhydrous toluene under Ar. After stirring overnight the solvent was removed in vacuo. Purification via flash chromatography yielded 0.278 g (1.34 mmol, 100% yield) of 1-(azidomethyl)-3-methoxy-5-nitrobenzene.
