Procedure

A mixture of 540 mg (2.1 mmol) of methyl 2-phenyl-1H-benzo[d]imidazole-7-carboxylate 9z and 3 mL (9 mmol) of 3N aqueous NaOH was refluxed in 8 mL of THF overnight. After cooling, the mixture was poured into ice water and acidified with conc. HCl. The resulting solid was filtered and dried to give 440 mg (86%) of phenyl-1H-benzo[d]imidazole-7-carboxylic acid, 9aa. MS m/z (M+H+) 238.9.
