Procedure

A solution of methyl[3-cyano-5-(trifluoromethyl)benzyl]{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}carbamate (35.0 mg, 0.06 mmol) (Example 36) in DMSO (248 μL) was cooled to 0° C. Next, K2CO3 (17.4 mg, 0.05 mmol) was added followed by 30% H2O2 (42.2 μL), and the reaction was slowly warmed to room temperature. After stirring at room temperature for 15 minutes, the mixture was diluted with EtOAc (50 mL) and poured into H2O (15 mL). The organic extract was washed with brine (10 mL), dried over Na2SO4, filtered, and concentrated. Purification by flash chromatography with 5% to 80% EtOAc/hexanes afforded methyl[3-(aminocarbonyl)-5-(trifluoromethyl)benzyl]{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}carbamate.
