fluorine addition

[imrober]

Hi,

I have something I'm concerned about. I'm trying to come up with a method for fluorination of an aniline ring. I would like to fluorinate the amino so that the product is Aryl-NHCH2CF3, for example. Does any one know if trifluorobromoethane could be used to synthesize the above product? If not is there another reagent I could use?

Thanks,

IR
