실험 절차
To anhydrous copper(II)chloride (6.3 g, 47 mmol) in acetonitrile (100 mL) was added tert-butyl nitrite (6.85 mL, 58 mmol), followed dropwise by a solution of 2-bromo-4-(trifluoromethoxy)aniline (10 g, 39 mmol) in acetonitrile (15 mL). The solution was stirred at ambient temperature for 1 hour then poured into hydrochloric acid (250 mL, 2M). The suspension formed was extracted with diethyl ether (2×250 mL) and the extracts were dried (MgSO4). Concentration yielded the title compound as an oil (7.82 g, 28 mmol).
