Procedure
(1-Cyclobutyl-3-methyl-2-oxo-2,3-dihydro-1H-benzoimidazol-5-yl)-acetonitrile (11.5 g) was diluted with sulfuric acid:water (1:1, 25 mL) and was heated to 110° C. for 4 hour then cooled and extracted into ethyl acetate, dried over sodium sulfate and concentrated to give 11.99 g of (1-Cyclobutyl-3-methyl-2-oxo-2,3-dihydro-1H-benzoimidazol-5-yl)-acetic acid.
