Participants

Reaction Steps

In a mixture of 1N NaOH solution (4.5 ml) and methanol (10 ml), methyl 2-[4-(2-butylbenzimidazol-1-yl)methylphenyl]benzoate (1.2 g) was heated for 3 hours under reflux. The reaction mixture was concentrated, and the concentrate was dissolved in water, washed with ether, then acidified with 1N-HCl to afford crystals. The crystals were collected by filtration and recrystallized from ethyl acetate - methanol to afford colorless crystals (0.64 g, 53%).
