Reaction Steps

A solution of 4N HCl in dioxane (15 mL) was added to tert-butyl (2S,4S)-2-(4-(4-(6-(2-((2S,4S)-1-(tert-butoxycarbonyl)-4-methyl-2-pyrrolidinyl)-1H-imidazol-4-yl)-2-naphthyl)phenyl)-1H-imidazol-2-yl)-4-methyl-1-pyrrolidinecarboxylate (200 mg. 0.285 mmol) in MeOH (5 mL) and stirred at ambient conditions for 2 hours, concentrated, and dried under vacuum. Tetra HCl salt (assume theoretical: 185 mg). LC-MS retention time 2.64 min; calcd. for C32H35N6: 503.29 m/z Found 503.20 [M+H]+. LC data was recorded on a Shimadzu LC-10AS liquid chromatograph equipped with a PHENOMENEX® Luna 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 5% methanol/95% water/0.1% TFA and Solvent B was 95% methanol/5% water/0.1% TFA. MS data was determined using a MICROMASS® Platform for LC in electrospray mode.
