disorder in main residue; R factor = 0.034; wR factor = 0.088; data-to-parameter ratio = 12.5. In the title compound, C14H18N2O3, the carboxylic group is tilted by 12.00 (4) with respect to the mean plane throught the benzimidazole ring system. The alcohol and carboxyl hydroxy groups are involved in intermolecular O—H O and O—H N hydrogen bonds, forming a two-dimensional network extending parallel the ab plane. The network is further stabilized by weak C—H O interactions. The sec-butyl group is disordered over two sets of sites with refined occupancies of 0.484 (4) and 0.516 (4).
