Reaction Steps

A solution of 2-(2-furyl)-5-nitrobenzimidazole (52 g, 0.2 mole) in 1 liter of absolute ethyl alcohol is reduced (Parr apparatus) using 5 percent palladium on carbon (50 percent wet) catalyst. An uptake of 44 lbs. (100 percent of theory) of hydrogen in one-half hr is noted. After the reduction is complete the catalyst is removed by filtration. The filtrate is used in part D.
