실험 절차

tert-Butyl {2-[3-(tert-butoxycarbonyl-phenethyl-amino)-propylsulfanyl]-benzoimidazol-1-yl}-acetate (Precursor J-01b, 199 mg, 0.38 mmol) is dissolved in a 1M HCl solution in ethyl acetate (1.89 ml). The resulting solution is stirred at rt for 1 h. The solvent is evaporated and the crude solid is dissolved in dichloromethane, the resulting organic phase is washed with a saturated aqueous NaHCO3 solution and with water. Evaporation of the solvent in vacuo and chromatography of the residue on silica-gel (dichloromethane/MeOH, 92:8) yields the title compound (107 mg) in 61% as a white solid: tR=2.62 min (LC-2), ESI-MS (pos.): m/z 510.49 [M+H]+.
