Procedure
To a solution of compound 3-(5-(4-(1H-imidazol-1-yl)phenyl)-1-(4-carbamoyl-2-methylphenyl)-1H-pyrrol-2-yl)propanoate (22.0 g, 48.3 mmol) in THF/H2O (v/v=1/1, 220 mL) was added LiOH.H2O (4.15 g, 96.6 mmol). The reaction solution was stirred at room temperature for 5 h. The THF was removed under reduced pressure and the aqueous solution was acidified with 10% HCl to pH=5. The solid was filtered and recrystallized from THF and water [1:1(v/v)] to afford 3-(5-(4-(1H-imidazol-1-yl)phenyl)-1-(4-carbamoyl-2-methylphenyl)-1H-pyrrol-2-yl)propanoic acid as a yellow solid (11.35 g, 55%).
