실험 절차

To a 0° C. solution of 3-chloro-4-((5-(2-(4-chloro-3-methoxyphenyl)propan-2-yl)-1-(4-fluoro-phenyl)-1H-imidazol-2-ylthio)methyl)-5-fluorobenzoic acid (0.94 g, 0.17 mmol), (S)-tert-butyl 2-amino-5-(tert-butoxycarbonylamino)pentanoate (0.050 g, 0.18 mmol) and HATU (0.067 g, 0.18 mmol) in DMF (4 mL) was added DIPEA (0.058 mL, 0.33 mmol). The ice bath was removed and the reaction was stirred for 2 h at room temperature. The reaction was quenched with satd NaHCO3 and diluted with EtOAc. The organic layer was washed with H2O (2×5 mL), brine, and dried with Na2SO4. The solvent was removed in vacuo and the residue was purified by column chromatography to afford 114 mg of (S)-tert-butyl 5-(tert-butoxycarbonylamino)-2-(3-chloro-4-((5-(2-(4-chloro-3-methoxyphenyl)propan-2-yl)-1-(4-fluorophenyl)-1H-imidazol-2-ylthio)methyl)-5-fluorobenzamido)pentanoate. The compound was then dissolved in 4N solution of HCl in dioxane and stirred for 2 h, when the reaction was determined to be complete by LCMS. Ether was added to the reaction mixture. Then the solids were collected by filtration and dried under vacuum to afford the title compound (75 mg). 1H-NMR (DMSO6, 400 MHz) δ 9.00 (d, J=8.3 Hz, 1H), 8.01 (s, 3H), 7.93 (s, 1H), 7.82-7.75 (m, 2H), 7.23 (d, J=8.5 Hz, 1H), 7.06-6.99 (m, 2H), 6.67-6.64 (m, 1H), 6.61-6.57 (m, 1H), 6.53-6.52 (m, 1H), 6.50-6.47 (m, 1H), 4.43-4.38 (m, 1H), 4.19 (s, 2H), 3.70 (s, 3H), 2.84-2.80 (m, 2H), 1.97-1.80 (m, 2H), 1.75-1.66 (m, 2H), 1.51 (m, 6H); MS (ES): 677 [M]+.
