Reaction Steps

(R)-{4-[7-(1-Isobutoxy-ethoxycarbamoyl)-heptanoylamino]-benzylamino}-phenyl-acetic acid cyclopentyl ester (50 mg, 0.08 mmol, 1 eq) was dissolved in DCM (0.5 mL) and stirred with 4M HCl in dioxane (0.2 mL) for 30 min. The resulting salt was concentrated, dissolved in methanol and purified by preparative HPLC to yield compound (83). LCMS purity 94%, m/z 496 [M++H]+, 1H NMR (300 MHz, MeOD), δ: 1.41-1.95 (16H, m, 8×CH2), 2.15-2.17 (2H, m, CH2), 2.40 (2H, t, J=7.2 Hz, CH2), 4.16 (2H, q, J=13.5 Hz, CH2), 5.12 (1H, s, CH), 5.27-5.30 (1H, m, CH), 7.40 (2H, d, J=8.7 Hz, Ar—H), 7.50-7.56 (5H, m, Ar—H), 7.67 (2H, d, J=8.7 Hz, Ar—H).
