You must first beat N and he will give you the stone of his Pokemon. You can then take it to dragonspiral tower and catch his Pokemon depending on the game.

You can't get Zekrom in White2 you can get it in Black2

Go to where the Zorark was standing and you will find N's Castle from there N will guide you.
