Reaktionsschritte
2-fluoronitrobenzene was treated with aniline in the prescence of K2CO3 in CH3CN and heated to reflux for 12 h. The solution is cooled, filtered and the solvent removed. The nitro group is reduced with catalytic hydrogenation and the diamine treated with CDI to give 1-phenyl-1,3-dihydro-benzoimidazol-2-one.
