実験手順

A mixture of 0.535 g of (4-benzoimidazol-1-yl-phenyl)-acetic acid methyl ester and 2 ml of an 1N aqueous solution of LiOH in 2 ml of THF is stirred for 3 hours at 45° C. The mixture obtained is allowed to cool to rt and acidified to pH 5 by addition of 0.5 N aqueous HCl. A solid precipitates and is collected by vacuum filtration. (4-Benzoimidazol-1-yl-phenyl)-acetic acid is obtained. ES-MS: 253.1 [M+H]+; single peak at tR=2.36 min (System 1).
