Participants

Reaction Steps

To a solution of 4-benzyloxy-l-ethyl-2-methyl-1H-benzimidazole (370 mg) in ethyl acetate (3.7 ml) was added 10% palladium on carbon (18 mg), and the mixture was stirred for 5 hours at ambient temperature under hydrogen atmosphere. Insoluble material was filtered off, and the filtrate was concentrated in vacuo. The residue was crystallized with diisopropyl ether to give 1-ethyl-4-hydroxy-2-methyl-1H-benzimidazole (220 mg).
