실험 절차

To a solution of {[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}[3-nitro-5-(trifluoromethyl)benzyl]amine (428 mg, 0.81 mmol) and methyl chloroformate (126 μL, 1.39 mmol) in CH2Cl2 (10 mL) was added N,N-diisopropylethylamine (566 μL, 3.25 mmol). The reaction was stirred at room temperature for twenty minutes and then was poured into H2O (25 mL). The mixture was extracted with EtOAc (70 mL), and the organic extracts were washed with brine (25 mL), dried over Na2SO4, filtered, and concentrated. Purification by flash chromatography with 2% to 20% EtOAc/hexanes afforded methyl {[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}[3-nitro-5-(trifluoromethyl)benzyl]carbamate.
