An efficient solidphasesynthesis of benzimidazoles is described. Polymer bound o-fluoronitroaromatic compound 2 was treated with an amine to give o-nitroaniline derivative 3. Reduction of 3 with NaBH4Cu(acac)2 followed by cyclization with an aryl imidate and cleavage with TFA gave 5. A library of benzimidazoles has been prepared in three steps in 70–95 % crude yield and 70–98 % purity. Final purified
