Procedure

To a solution of ethyl 3-(5-(4-(1H-imidazol-1-yl)phenyl)-1-(4-(aminomethyl)-2-methylphenyl)-1H-pyrrol-2-yl)propanoate (30C) (300 mg) in THF/H2O (v/v=1/1, 6 mL) was added lithium hydroxide monohydrate (50.4 mg, 2.10 mmol). The solution was stirred at room temperature overnight. THF was removed under reduced pressure and the resulting solution was acidified with 10% hydrochloric acid to pH=6.0. The resulting precipitate was isolated by centrifuge, rinsed with water, dried under reduced pressure and purified by prep-HPLC to afford 3-(5-(4-(1H-imidazol-1-yl)phenyl)-1-(4-(aminomethyl)-2-methylphenyl)-1H-pyrrol-2-yl)propanoic acid (30D) (170 mg, 74%) as a yellow solid.
