Procedure

To a solution of methyl[3-amino-5-(trifluoromethyl)benzyl]{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}carbamate (8 mg, 0.014 mmol) (Example 33) and methanesulfonyl chloride (3.3 μL, 0.043 mmol) in CH2Cl2 (1 mL) was added N,N-diisopropylethylamine (15 μL, 0.086 mmol). The reaction was stirred at room temperature for thirty minutes and then was poured into H2O (10 mL). The mixture was extracted with EtOAc (50 mL), and the organic extracts were washed with brine (10 mL), dried over Na2SO4, filtered, and concentrated. Purification by preparative thin layer chromatography with 25% EtOAc/hexanes followed by a preparative thin layer chromatography in 2:2:1 (CH2Cl2:Hex:Et2O) and then a third and final purification by silica gel chromatography with 2% to 25% EtOAc/hexanes afforded methyl{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}[3-[(methylsulfonyl)amino]-5-(trifluoromethyl)benzyl]carbamate. Rf=0.40 (25% EtOAc/hexanes). 1H NMR (C6D6, 500 MHz, 70° C.) δ 7.69 (s, 1H), 7.52 (s, 1H), 7.38-7.25 (m, 3H), 7.08-7.04 (m, 2H), 6.86 (s, 1H), 6.30 (d, J=8.5 Hz, 1H), 4.40 (broad singlet, 2H), 4.04-3.99 (m, 2H), 3.33 (s, 3H), 3.26 (s, 3H), 2.74 (m, 1H), 2.67 (s, 3H), 1.22 (d, J=6.5 Hz, 6H).
