실험 절차
4-tert-Butyl-2-chlorophenyl methyl carbonate (36.0 g, 0.15 mol) was dissolved in conc. H2SO4 (100 mL) at 0° C. KNO3 (0.53 g, 5.2 mmol) was added in portions over 25 min. The reaction was stirred for 1.5 h and poured into ice (200 g). The aqueous layer was extracted with dichloromethane. The combined organic layers were washed with aq. NaHCO3, dried over Na2SO4 and concentrated under vacuum to give 4-tert-butyl-2-chloro-5-nitrophenyl methyl carbonate (41.0 g), which was used without further purification.
