Procedure
[3,5-Bis(trifluoromethyl)benzyl]{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}amine (40.3 mg, 0.073 mmol) (Example 20) was dissolved in CH2Cl2 (3 mL) and the solution was cooled to −78° C. Chlorosulfonyl isocyanate (32 μL, 0.367 mmol) was added dropwise by syringe. The reaction was stirred at −78° C. for 15 minutes, and then at 0° C. for 20 minutes. The reaction was then poured into H2O (15 mL) and saturated NaHCO3 (15 mL) was added. The mixture was extracted with CH2Cl2 (2×25 mL). The organic extracts were dried over Na2SO4, filtered, and concentrated. Purification of the residue by flash chromatography with 50% EtOAc/hexanes afforded N-[3,5-bis(trifluoromethyl)benzyl]-N-{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}urea.
