Reaction Steps

To a slurry of 2-{5-[4-(6-{2-[1-(2-Methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-naphthalen-2-yl)-phenyl]-1H-imidazol-2-yl}-pyrrolidine-1-carboxylic acid tert-butyl ester (0.1 g, 0.14 mmol) in MeOH (0.15 mL) was added HCl in dioxanes (4 M, 0.7 mL). The resulting solution was stirred at room temperature for 1 hour and diluted with Et2O. The resulting precipitate was filtered and dried to provide {2-Methyl-1-[2-(5-{6-[4-(2-pyrrolidin-2-yl-3H-imidazol-4-yl)-phenyl]-naphthalen-2-yl}-1H-imidazol-2-yl)-pyrrolidine-1-carbonyl]-propyl}-carbamic acid methyl ester trihydrochloric acid salt (0.09 g, 87%) as a white powder. LCMS-ESI+: calc'd for C37H41N7O3: 631.3 (M+). Found: 632.7 (M+H+).
