Prepared using General Procedure 6. To a suspension of methyl 2-((4-(5-(4′-methyl-[1,1′-biphenyl]-4-yl)-1,2,4-oxadiazol-3-yl)benzyl)amino)acetate INT-77 (50 mg, 0.121 mmol) and 2-fluoro-4-(2-(4-methoxy-2-(trifluoromethyl)phenyl)acetamido)benzoic acid INT-78 (44.9 mg, 0.121 mmol) in DMF (2 mL) were added HATU (50.6 mg, 0.133 mmol) and TEA (42.1 μL, 0.302 mmol). The reaction mixture was stirred at room temperature. After 60 h the reaction mixture was diluted with EA (20 mL) and washed with NaHCO3 (2×20 mL) and 1 M HCl (2×20 mL). The organics were dried over MgSO4 and concentrated in vacuo to afford 91 mg (98%) of methyl 2-(2-fluoro-4-(2-(4-methoxy-2-(trifluoromethyl)phenyl)acetamido)-N-(4-(5-(4′-methyl-[1,1′-biphenyl]-4-yl)-1,2,4-oxadiazol-3-yl)benzyl)benzamido)acetate INT-79 as a pale yellow solid. LCMS-ESI (m/z) calculated for C42H34F4N4O6: 766; found 767 [M+H]+, tR=3.27 min (Method 10).
