Prepared using General Procedures 2 and 8: To a stirring solution of 4-octylbenzoic acid (42 mg, 0.178 mmol) in DCM (0.5 mL) were added DMF (1 drop) and oxalyl chloride (0.016 mL, 0.190 mmol). The reaction mixture was stirred at room temperature for 2 h. To this mixture was added a solution of tert-butyl 2-(N-(4-hydroxybenzyl)-4-(2-(4-methoxyphenyl)acetamido)benzamido)acetate INT-7 (60 mg, 0.119 mmol) and TEA (0.050 mL, 0.357 mmol) in DCM (1 mL). The reaction was stirred at room temperature for 18 h then TFA (1 mL) was added. After stirring for 2 h, the solvent was concentrated and the product was purified by preparative HPLC to provide to afford 15.3 mg (19%) of 2-(4-(2-(4-methoxyphenyl)acetamido)-N-(4-((4-octylbenzoyl)oxy)benzyl)benzamido)acetic acid 40. LCMS-ESI (m/z) calculated for C40H44N2O7: 664; found 665 [M+H]+, tR=10.33 min (Method 4). 1H NMR (400 MHz, DMSO) δ 10.31 (s, 1H), 8.04 (d, J=8.2 Hz, 2H), 7.65 (d, J=8.5 Hz, 2H), 7.50-7.21 (m, 10H), 6.89 (d, J=8.4 Hz, 2H), 4.63 (d, J=36.7 Hz, 2H), 3.95 (d, J=33.1 Hz, 2H), 3.73 (s, 3H), 3.58 (s, 2H), 2.76-2.64 (m, 2H), 1.61 (s, 2H), 1.36-1.10 (m, 10H), 0.86 (t, J=6.8 Hz, 3H).
