Reaction Steps

To a solution of 2-(2-Amino-phenylamino)-benzoic acid methyl ester (75 mg, 0.31 mmol) in THF (1.0 mL) is added COI (100 mg, 0.62 mmol) at room temperature. The mixture is stirred at the same temperature for 16 hours. Then 3 mL of 1.0 M HCl solution is added along with 20 mL of water. The mixture is extracted with EtOAc (3×30 mL) and the organic layers are combined, dried and concentrated to give crude product. Purification by flash column chromatography affords 65 mg (78%) of 2-(2-Oxo-2,3-dihydro-benzimidazol-1-yl)-benzoic acid methyl ester.
