Procedure

N-Chlorosuccinimide (6.01 mg, 0.045 mmol) was added to a stirred solution of a TFA salt of methyl ((1S)-1-(((1R,3S,5R)-3-(4-(6-(4-(2-((1R,3S,5R)-2-((2S)-2-((methoxycarbonyl)amino)-3-methylbutanoyl)-2-azabicyclo[3.1.0]hex-3-yl)-1H-imidazol-4-yl)phenyl)-2-quinolinyl)-1H-imidazol-2-yl)-2-azabicyclo[3.1.0]hex-2-yl)carbonyl)-2-methylpropyl)carbamate (Example 80) (26 mg, 0.022 mmol) in DMF (0.5 mL) and the reaction mixture was stirred at 50° C. for 16 h. The reaction was diluted with MeOH, filtered and purified by preparative HPLC (H2O-MeOH with 0.1% TFA buffer) to yield two products: 1) A TFA salt of methyl ((1S)-1-(((1R,3S,5R)-3-(4-chloro-5-(6-(4-(4-chloro-2-((1R,3S,5R)-2-((2S)-2-((methoxycarbonyl)amino)-3-methylbutanoyl)-2-azabicyclo[3.1.0]hex-3-yl)-1H-imidazol-5-yl)phenyl)-2-quinolinyl)-1H-imidazol-2-yl)-2-azabicyclo[3.1.0]hex-2-yl)carbonyl)-2-methylpropyl)carbamate (12.4 mg) as yellow solid. LC-MS retention time 3.871 min; m/z 882.55 (MH+). LC data was recorded on a Shimadzu LC-10AS liquid chromatograph equipped with a PHENOMENEX® Luna 3u C18 2.0×50 mm column using a SPD-10AV UV-Vis detector at a detector wave length of 220 nM. The elution conditions employed a flow rate of 0.8 mL/min, a gradient of 100% Solvent A/0% Solvent B to 0% Solvent A/100% Solvent B, a gradient time of 4 min, a hold time of 1 min, and an analysis time of 5 min where Solvent A was 10% MeOH/90% H2O/0.1% trifluoroacetic acid and Solvent B was 10% H2O/90% MeOH/0.1% trifluoroacetic acid. MS data was determined using a MICROMASS® Platform for LC in electrospray mode. 1H NMR (400 MHz, MeOD) δ ppm 8.53 (d, J=8.8 Hz, 1H), 8.26 (d, J=8.8 Hz, 1H), 8.23 (s, 1H), 8.17 (s, 2H), 7.82-7.93 (m, 4H), 5.16 (dd, J=8.8, 5.3 Hz, 1H), 5.06 (t, J=7.2 Hz, 1H), 4.53-4.63 (m, 2H), 3.68-3.76 (m, 2H), 3.67 (s, 6H), 2.44-2.60 (m, 4H), 2.11-2.24 (m, 2H), 1.97-2.09 (m, 2H), 1.09-1.18 (m, 2H), 1.03 (dd, J=6.8, 3.3 Hz, 6H), 0.95 (dd, J=6.8, 2.4 Hz, 6H), 0.75-0.87 (m, 2H). 2) A TFA salt of methyl ((1S)-1-(((1R,3S,5R)-3-(4-(6-(4-(4-chloro-2-((1R,3S,5R)-2-((2S)-2-((methoxycarbonyl)amino)-3-methylbutanoyl)-2-azabicyclo[3.1.0]hex-3-yl)-1H-imidazol-5-yl)phenyl)-2-quinolinyl)-1H-imidazol-2-yl)-2-azabicyclo[3.1.0]hex-2-yl)carbonyl)-2-methylpropyl)carbamate (4.8 mg) as yellow solid. LC-MS retention time 2.98 min; m/z 848.60 (MH+).
