Reaction Steps

4M HCl in dioxane (10 mL, 40.0 mmol) was added to a stirred solution of a TFA salt of (1R,3S,5R)-tert-butyl 3-(5-(6-(2-((1R,3S,5R)-2-(tert-butoxycarbonyl)-2-azabicyclo[3.1.0]hexan-3-yl)-1H-benzo[d]imidazol-5-yl)naphthalen-2-yl)-1H-imidazol-2-yl)-2-azabicyclo[3.1.0]hexane-2-carboxylate (151 mg) in DCM (3 mL). Precipitate formed immediately. The suspension was agitated for 30 min. The volatile components were evaporated under vacuum. The crude residue was taken in DCM (3 mL) and TFA (2 mL) was added. The solution was agitated for 1 h. The volatile components were evaporated under reduced pressure. The residue was taken into MeOH and filtered through a Strata XC MCX cartridge. The cartridge was washed with methanol and the compound was release from the cartridge by eluting with a solution of 2M of ammonia/methanol. The ammonia/methanol filtrate was evaporated under reduced pressure to yield 6-(6-(2-((1R,3S,5R)-2-azabicyclo[3.1.0]hexan-3-yl)-1H-imidazol-4-yl)naphthalen-2-yl)-2-((1R,3S,5R)-2-azabicyclo[3.1.0]hexan-3-yl)-1H-benzo[d]imidazole (79 mg, 0.17 mmol) as yellow solid. LC-MS retention time 1.130 min; m/z 473.35 (MH+). LC data was recorded on a Shimadzu LC-10AS liquid chromatograph equipped with a Waters Sunfire 5u C18 4.6×30 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 4 mL/min, a gradient of 100% Solvent A/0% Solvent B to 0% Solvent A/100% Solvent B, a gradient time of 2 min, a hold time of 1 min, and an analysis time of 3 min where Solvent A was 10% MeOH/90% H2O/0.1% TFA and Solvent B was 10% H2O/90% MeOH/0.1% TFA. MS data was determined using a MICROMASS® Platform for LC in electrospray mode. 1H NMR (500 MHz, MeOD) δ ppm 8.19 (s, 1H), 8.07 (s, 1H), 7.92 (dd, J=8.6, 5.8 Hz, 2H), 7.88 (s, 1H), 7.82 (dd, J=5.8, 1.5 Hz, 2H), 7.61-7.66 (m, 2H), 7.51 (s, 1H), 4.24-4.35 (m, 2H), 3.11 (td, J=6.1, 2.4 Hz, 1H), 3.06 (td, J=6.0, 2.6 Hz, 1H), 2.40-2.53 (m, 2H), 2.18-2.33 (m, 2H), 1.69-1.76 (m, 1H), 1.62-1.69 (m, 1H), 0.88 (ddd, J=6.6, 4.3, 2.6 Hz, 1H), 0.79-0.84 (m, 1H), 0.61-0.68 (m, 1H), 0.55-0.60 (m, 1H).
