Reaction Steps
2 g of dry 3,5-dimethoxyphenol was dissolved in 25 mL dry THF and cooled in an ice bath. To this solution was added 2.25 g of diethylazodicarboxylate (DEAD), 6 g of triphenylphosphine and 1 mL of ammonium chloride (NH4Cl). The mixture was stirred for 20 minutes. The mixture was warmed to room temperature and stirred for an additional 30 minutes. Silica gel was added to remove DEAD, triphenylphosphine, and excess ammonia, yielding 3,5-dimethoxyaniline.
