Reaction Conditions

Reaction Steps

4-(Difluoromethoxy)phenol (500 mg, 3.12 mmol) was dissolved in DCE (3 mL). The reaction mixture was cooled to 0° C. and nitric acid (0.488 mL, 10.92 mmol) was added dropwise over 10 min. The reaction mixture was stirred for a further hour at 0° C., then poured into an ice/water mix (5 g in 5 mL). DCE (10 mL) was added and the layers separated. The organic layer was dried (MgSO4) and evaporated to dryness to give a crude brown oil (550 mg). Material was carried forward without further purification, as no separation between products was found in TLC solvent systems used.
