The 1,3-dihydro-1-(2-bromoethyl)-3-isopropenyl-2H-benzimidazol-2-one was used as a starting material for making of the title compound. This compound treated with piperizine in the presence of TBAB as a catalyst which is treated with m-trifluoromethyl bromobenzene, in the presence of base and palladium acetate than followed by passing HCl gas to produced corresponding title compound in good yield with high purity. The structures of all the synthesized compounds were confirmed by IR, 1 H NMR, C 13NMR and Mass Spectral data.
