Procedure

To a solution of 1-[3,5-bis(trifluoromethyl)phenyl]-2-({[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}amino)ethanol (Example 6 Step B, 325.0 mg, 0.561 mmol) in CH2Cl2 (15 mL) was added BOC2O (122 mg, 0.561 mmol) and DIPEA (98 μL, 0.561 mmol). The reaction was stirred at room temperature. After 5 hours, additional BOC2O (50 mg, 0.229 mmol) and DIPEA (50 μL, 0.287 mmol) were added. The reaction was stirred at room temperature for 48 hours. The reaction was then concentrated to ˜2 mL, diluted with hexanes (8 mL) and purified by flash chromatography with 10 to 20% EtOAc/hexanes to afford tert-butyl{2-[3,5-bis(trifluoromethyl)phenyl]-2-hydroxyethyl}{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}carbamate. Rf=0.38 (25% EtOAc/hexanes). LCMS=580.3 (M+1−BOC)+. 1H NMR (CD2Cl2, 500 MHz) δ 7.78 (s, 1H), 7.54-7.67 (m, 4H), 7.23-7.33 (m, 2H), 6.90-6.95 (m, 2H), 3.15-4.82 (m, 9H), 2.87 (m, 1H), 1.19-1.43 (m, 15H).
