Participants

Reaction Steps

Methyl 4-fluoro-5-(2-fluoro-4-iodophenylamino)-1-methyl-1H-benzo[d]imidazole-6-carboxylate (2.15 g, 4.8 mmoles) is dissolved in a mixture of THF (30 ml), MeOH (10 ml) and H2O (5 ml) and LiOH (1.16 g, 4.8 mmoles) is added. The mixture is stirred at room temperature for 2 hours. Solvents are removed under reduced pressure and 1N HCl is added. The aqueous layer is extracted with chloroform. The organic layers are combined, washed with brine, dried (Na2SO4) and concentrated under reduced pressure to obtain the title compound.
