실험 절차

tert-Butyl {2-[3-(tert-butoxycarbonyl-phenethyl-amino)-propylsulfanyl]-benzoimidazol-1-yl}-acetate (Precursor J-01b, 12.7 mg, 0.025 mmol) is suspended in an aqueous 0.2 M NaOH solution (0.67 ml). After addition of THF (1.3 ml) the resulting solution is allowed to stir overnight at rt. It is then treated with 1 M aqueous HCl (3.35 ml), water (2 ml) and dichloromethane (3 ml). The phases are separated and the dichloromethane is removed under reduced pressure. Drying under high vacuum yields the pure title compound: tR=2.12 min (LC-2), ESI-MS (neg.): m/z 470.47 [M−H]+; 1H-NMR (DMSO-d6): δ 1.31 (s, 9H, tBu), 1.88 (quint., 2H, SCH2CH2), 2.73 (m, 2H, CH2Ph), 3.24 (t, 2H), 3.28-3.36 (m, 4H), 4.94 (s, 2H, CH2CO2), 7.13 (m, 5Harom), 7.23 (t, 2Harom), 7.42-7.50 (m, 2Harom).
