실험 절차

70% HNO3 (5.1 mL, 84.76 mmol, 1.2 equiv) was added dropwise to a mixture of 2-isopropylaniline (10 mL, 9.55 g, 70.63 mmol, 1 equiv) in 70 mL of conc. sulfuric acid at 0° C. The reaction mixture was stirred at this temperature for 30 minutes and then poured onto ice. The aqueous mixture was extracted with EtOAc (2×150 mL). The organic layers were combined and washed with sat'd NaHCO3. After evaporation, the residue was purified by column chromatography on silica gel using EtOAc/hexanes (3/7) to give 2 g of product (16%) as a dark red oil.
