A crude solution of 4-(3-(tert-butoxy)-2-(4-methoxybenzamido)-3-oxopropyl)-2-methoxyphenyl 4-(heptyloxy)benzoate in DCM (1 mL) was treated with TFA (0.1 mL) and stirred overnight at 30° C. The solvent was evaporated and the residue was purified by preparative HPLC to give 16.9 mg (48%) of 3-(4-(4-(heptyloxy)benzoyl)oxy)-3-methoxyphenyl)-2-(4-methoxybenzamido)propanoic acid 2. LCMS-ESI (m/z) calculated for C32H37NO8: 563. Found 564 [M+H]+, tR=11.01 min (Method 2). 1H NMR (400 MHz, DMSO) δ 12.79 (s, 1H), 8.57 (d, J=8.1 Hz, 1H), 8.00 (d, J=9.0 Hz, 2H), 7.82 (d, J=8.9 Hz, 2H), 7.13 (d, J=1.7 Hz, 1H), 7.11-7.03 (m, 3H), 6.99 (d, J=8.9 Hz, 2H), 6.92 (dd, J=8.1, 1.7 Hz, 1H), 4.61 (ddd, J=10.8, 8.1, 4.4 Hz, 1H), 4.07 (t, J=6.5 Hz, 2H), 3.80 (s, 3H), 3.69 (s, 3H), 3.20 (dd, J=13.8, 4.2 Hz, 1H), 3.08 (dd, J=13.7, 10.7 Hz, 1H), 1.84-1.66 (m, 2H), 1.51-1.17 (m, 8H), 0.87 (t, J=6.9 Hz, 3H).
