HCID 86637890, compound → ethyl (4-hydroxy-2-methyl-1H-benzimidazol-1-yl)acetate

Participants

Reaction Steps

To a solution of ethyl [4-(benzyloxy)-2-methyl-1H-benzimidazol-1-yl]acetate (2.57 g) in a mixture of EtOH (25.7 mL) and THF (12.9 mL) was added 10% palladium on carbon (50% wet, 0.78 g) at ambient temperature, and the resultant mixture was hydrogenated under atmospheric pressure of hydrogen for 2 hours. The catalyst was removed by filtration and evaporated in vacuo to give crude solid. The crude solid was recrystallized from solvent (EtOAc:n-hexane) to give ethyl (4-hydroxy-2-methyl-1H-benzimidazol-1-yl)acetate (1.73 g) as a white solid.
