Reaction Steps

(S)-2-[4-({[2-(1-Isobutoxy-ethoxycarbamoyl)-benzo[b]thiophen-6-ylmethyl]-amino}-methyl)-benzylamino]-3-phenyl-propionic acid cyclopentyl ester was dissolved in DCM (2 mL) and MeOH (2 mL) and treated with TFA (1 mL). The mixture was stirred for 1 h at r.t then concentrated to dryness and DCM (5 mL) and heptane (5 mL) added. The mixture was evaporated to dryness. This process was repeated three times to yield compound (104) (20 mg, 59%) as a oil. LCMS purity 95%, m/z 558 [M++H]+, 1H NMR (300 MHz, MeOD), δ: 1.25-1.91 (8H, m, 4×CH2), 3.12-3.47 (2H, m, CH2), 4.26 (1H, m, CH), 4.33 (2H, d, J=5.5 Hz, CH2), 4.36 (2H, s, CH2), 4.43 (1H, s, CH2), 5.16 (1H, s, CH), 5.13 (1H, m, CH), 7.25-7.37 (6H, m, ArH), 7.54-7.63 (4H, m, ArH), 7.94 (2H, m, ArH), 8.09 (1H, s, ArH).
