Reaction Steps

To a solution of (S)-4-{[(R)-7-(3,5-dichloro-4-fluoro-phenyl)-5-methyl-6-oxo-5-(4-trifluoromethoxy-benzyl)-6,7-dihydro-5H-imidazo[1,2-a]imidazole-3-carbonyl]-amino}-4-(1-methyl-1-pyridin-2-yl-propylcarbamoyl)-butyric acid tert-butyl ester (116 mg, 0.142 mmol) in 2 mL of CH2Cl2 was added HCl in dioxane (0.177 mL, 0.708 mmol). The reaction mixture was stirred at room temperature for 6 h. An additional portion of HCl in dioxane (0.177 mL, 0.708 mmol) was added, and the reaction mixture was stirred for 4 h and then concentrated to a colorless oil. The residue was purified by reverse-phase HPLC (20-90% CH3CN/H2O, 0.1% TFA) to give 45 mg (42%) of the title compound, isolated as the TFA salt, m/z 763.8 [M+1]+.
