Reaction Steps

2-Biphenyl-4-yl-1H-benzoimidazole-4-carboxylic acid methyl ester (180 mg, 0.54 mmol) was taken in THF (20 mL) and was refluxed with 5N NaOH (5 mL) solution for 14 h. It was then cooled to room temperature; THF was removed under reduced pressure to obtain a thick mass. This residue was diluted with water (10 mL) and adjusted pH to 2 with conc. hydrochloric acid. The precipitated solid was filtered, washed with water and dried in a vacuum oven to obtain compound the required compound as a pale yellow solid.
