Prepared using General Procedure 4: A solution of 4-(2-(((benzyloxy)carbonyl)amino)-3-(tert-butoxy)-3-oxopropyl)-2-methoxyphenyl 4-(heptyloxy)benzoate INT-3 (5.46 g, 8.81 mmol) and AcOH (5 mL) in MeOH (150 mL) was passed through the H-cube system with 10% Pd/C as a catalyst at 1 mL/min and 45° C. The reaction mixture was evaporated, dissolved in DCM (50 mL), and washed with saturated aqueous NaHCO3 (200 mL). The organic layer was dried over MgSO4 and concentrated to afford 3.93 g (92%) of 4-(2-amino-3-(tert-butoxy)-3-oxopropyl)-2-methoxyphenyl 4-(heptyloxy)benzoate INT-5. LCMS-ESI (m/z) calculated for C28H39NO6: 485; found 430 [M+H-tBu]+, tR=2.15 min (Method 4). 1H NMR (400 MHz, DMSO) δ 8.06-7.99 (m, 2H), 7.12-7.05 (m, 3H), 7.02-6.98 (d, J=1.9 Hz, 1H), 6.85-6.78 (dd, J=8.1, 1.8 Hz, 1H), 4.11-4.03 (t, J=6.5 Hz, 2H), 3.71 (s, 3H), 3.51-3.45 (t, J=6.9 Hz, 1H), 2.87-2.73 (dt, J=16.9, 6.5 Hz, 2H), 1.91 (s, 2H), 1.79-1.69 (p, J=6.8 Hz, 2H), 1.47-1.23 (m, 17H), 0.90-0.83 (m, 3H).
