Itachi never tried to kill Obito directly, they had a deal(something you seem to forget). Also if Konan, Torune and Foo could figure out how Kamui's intangibility(the only thing Minato worked a plan against) works then Minato isn't special there, like at all... Those three only lacked the speed to handle it, Itachi doesn't as he is faster than Konan, Obito, Foo and Torune easily. If they never had the deal then I'm sure Itachi would of killed Obito soon after joining Akatsuki.
