Reaction Steps

A crude solution of (S)-4-(3-(tert-butoxy)-2-(4-(tert-butyl)benzamido)-3-oxopropyl)phenyl 4-(heptyloxy)benzoate in DCM (1 mL) was treated with TFA (0.15 mL) and stirred overnight at 30° C. The solvent was evaporated and the residue was purified by preparative HPLC to give 12.3 mg (33%) of (S)-2-(4-(tert-butyl)benzamido)-3-(4-((4-(heptyloxy)benzoyl)oxy)phenyl)propanoic acid 57. LCMS-ESI (m/z) calculated for C34H41NO6: 559. Found 560 [M+H]+, tR=12.14 min (Method 2). 1H NMR (400 MHz, DMSO) δ 12.76 (s, 1H), 8.65 (d, J=8.2 Hz, 1H), 8.03 (d, J=8.9 Hz, 2H), 7.75 (d, J=8.6 Hz, 2H), 7.47 (d, J=8.6 Hz, 2H), 7.38 (d, J=8.6 Hz, 2H), 7.15 (d, J=8.5 Hz, 2H), 7.09 (d, J=9.0 Hz, 2H), 4.63 (ddd, J=10.8, 8.2, 4.4 Hz, 1H), 4.07 (t, J=6.5 Hz, 2H), 3.22 (dd, J=13.9, 4.3 Hz, 1H), 3.10 (dd, J=13.8, 10.8 Hz, 1H), 1.81-1.66 (m, 2H), 1.50-1.20 (m, 8H), 1.29 (s, 9H), 0.87 (t, J=6.9 Hz, 3H).
