Procedure

174 mg (0.376 mmol) of methyl 2-{6-[(2-butyl-4-chloro-5-hydroxymethyl-1H-imidazol-1-yl)methyl]quinolin-2-yl}benzoate obtained in Example 3 were mixed with 30.0 mg (0.751 mmol) of sodium hydroxide, 32 ml of water and 3 ml of ether and the mixture was stirred at room temperature for 24 hours. After concentrated under reduced pressure, the concentrate was partitioned between water and ether. The aqueous layer was acidified with 1N hydrochloric acid and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate followed by filtration. The resulting filtrate was concentrated under reduced pressure to obtain 134 mg of 2-{6-[(2-butyl-4-chloro-5-hydroxymethyl-1H-imidazol-1-yl)methyl]quinolin-2-yl}benzoic acid.
